The AD9554 low-loop-bandwidth clock translator provides jitter cleanup and synchronization for many systems, including synchronous optical networks (SONET/SDH). It generates an output clock synchronized to up to four external input references. The digital PLL (DPLL) reduces input time jitter and phase noise associated with the external references. The digitally controlled loop and holdover circuitry continues to generate a low-jitter output clock even when all reference inputs have failed. Eight differential clock outputs at frequencies from 430 kHz to 941 MHz are individually configurable for HCSL-, LVDS-, or LVPECL compatibility. The devices support GR-1244 Stratum 3 stability in holdover mode, Telcordia GR‑253 jitter specifications in up to OC-192 systems, and ITU-T G.8262 synchronous Ethernet slave clocks. Operating on 1.8-V and 3.3-V supplies, the AD9554 dissipates 940 mW in typical configurations and 174 mW in power-down mode. Available in a 72-lead LFCSP packages, it is specified from 40C to +85C and priced at $21.33 in 1000s.

Continuous-rate 6.5-Mbps to 8.5-Gbps Clock and Data Recovery IC

The ADN2913 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 6.5 Mbps to 8.5 Gbps, automatically locking to all data rates without an external reference clock. Its jitter performance exceeds all SONET/SDH requirements, including jitter transfer, jitter generation, and jitter tolerance. It provides manual or automatic slice adjust and manual sample phase adjusts; and users can select a limiting amplifier, adaptive or manually adjustable equalizer, or bypass at the input. The receiver front-end loss of signal (LOS) detector circuit indicates when the input signal level has fallen below a programmable threshold. Hysteresis prevents chatter at the LOS output. The input signal strength can be read through the I2C registers. The device supports pseudorandom binary sequence (PRBS) generation, bit error detection, and input data rate readback features. Operating on 1.2-V, 1.8-V, and 3.3-V supplies, the ADN2913 dissipates 388 mW at 4.25 Gbps. Available in a 24-lead LFCSP package, it is specified from 40C to +85C and priced at $29.95 in 1000s.

695-MHz to 2700-MHz Quadrature Demodulator includes fractional-N PLL, VCO

The ADRF6820 highly integrated demodulator and synthesizer is ideally suited for next-generation communication systems. The feature rich device consists of a high-linearity broadband I/Q demodulator, a fractional-N phase-locked loop (PLL), a low phase noise multicore voltage-controlled oscillator (VCO, a 2:1 RF switch, a tunable RF balun, a programmable RF attenuator, and two low dropout (LDO) regulators. The high isolation 2:1 RF switch and tunable RF balun support two single-ended, 50-Ω terminated RF inputs. The programmable attenuator offers a 0-dB to 15-dB attenuation range with a 1‑dB step size to ensure an optimal differential RF input level. The differential local oscillator (LO) input signal can be generated externally via a high-frequency, low-phase-noise LO signal or internally via the fractional-N synthesizer, which enables continuous LO coverage from 356.25 MHz to 2850 MHz. The PLL reference input supports a wide frequency range; divide or multiply blocks can increase or decrease the reference frequency to the desired value before it is passed to the phase frequency detector (PFD). When selected, the output of the fractional-N synthesizer is applied to a divide-by-2 quadrature phase splitter. From the external LO path, a 1 LO signal can be applied to the built-in polyphase filter, or a 2 LO signal can be used with the divide-by-2 quadrature phase splitter to generate the quadrature LO inputs to the mixers. Operating on 3.3-V and 5-V supplies, the ADRF6820 dissipates 1.4 W with internal PLL and VCO and 1.1 W with an external filter. Available in a 40-lead LFCSP package, it is specified from 40C to +85C and priced at $12.98 in 1000s.

30-MHz to 4.5-GHz RF Detector has 45-dB dynamic range

The ADL5506 complete, low-cost RF detector provides a 45-dB dynamic range over the 30-MHz to 4.5-GHz frequency range. Its high sensitivity allows measurement of low power levels, thus reducing the amount of power that needs to be coupled to the detector. The output, proportional to the logarithm of the input power level, is scaled to 18 mV/dB at 900 MHz, increasing from 0.14 V to 1 V as the input signal increases from 1.25 mV rms (−45 dBm) to 224 mV rms (0 dBm). For convenience, the signal is internally ac-coupled, using a 5-pF capacitor and a broadband 50-Ω match. This high-pass coupling determines the lowest operating frequency and allows the source to be dc grounded. Intended for use in a wide variety of wireless terminal devices, the detector provides a wide dynamic range, high accuracy, and excellent temperature stability. Operating with a single 2.5-V to 5.5-V supply, the ADL5506 consumes 3.8 mA when enabled and 1 A when disabled.

1100-MHz Variable-Gain Amplifiers and Baseband Programmable Filters

The ADRF6518 matched pair of fully differential low-noise, low-distortion programmable filters and variable-gain amplifiers (VGAs) can reject large out-of-band interferers while reliably boosting the wanted signal, thus reducing the bandwidth and resolution requirements on the analog-to-digital converters (ADCs). The excellent channel-to-channel match and high spurious-free dynamic range over all gain and bandwidth settings make it ideal for quadrature-based (IQ) communication systems with dense constellations, multiple carriers, and nearby interferers. Amplifier gain, filter corner frequency, and other features are programmable via an SPI-compatible serial port. The VGAs preceding the filters offer 24-dB of continuous control with 9-dB, 12-dB, and 15‑dB fixed-gain options, and set the differential input impedance to 400-Ω. The filters provide a six-pole Butterworth response with 0.5-dB corner frequencies from 1 MHz to 63 MHz in 1 MHz steps. For operation beyond 63 MHz, the filter can be disabled and completely bypassed, thereby extending the −3 dB bandwidth up to 1100 MHz. A wideband peak detector can monitor the peak signal at the filter inputs. The VGAs that follow the filters provide 24-dB of continuous gain control with fixed 12-dB, 15-dB, 18-dB, and 21-dB gain options. The output buffers offer an additional 3 dB or 9 dB gain, provide a differential output impedance of less than 10 Ω, and can drive 1.5 V p-p into 400-Ω loads at better than 65-dBc HD3. The output common-mode voltage, which defaults to VPS/2, can be adjusted down to 900 mV via the VOCM pin. Independent dc offset correction loops can be disabled if fully dc-coupled operation is desired. Operating on a single 3.15-V to 3.45-V supply, the ADRF6518 draws 400 mA max when enabled and 1 mA max when disabled. Available in a 32-lead, exposed pad LFCSP package, it is specified over from 40C to +85C and priced at $11.95 in 1000s.

High-voltage, latch-up proof, Dual SPST Switches

The ADG5421 and ADG5423 latch-up immune CMOS analog switches contain two independent single-pole/single-throw (SPST) switches. Each switch conducts equally well in both directions when on, and blocks signal levels up to the supplies when off. The input signal range extends to the power supplies. Their ultralow on resistance and on-resistance flatness make the switches ideal for data acquisition and gain switching applications where low distortion is critical; and their latch-up immune construction and 8-kV HBM ESD rating increase their robustness in harsh environments. The ADG5421 has two switches that are turned on with a Logic 1 input. The ADG5423 has one switch that is turned on with a Logic 1 input and one switch that is turned off; break-before-make switching action makes it useful in multiplexer applications. Operating on 9-V to 40-V or 9-V to 22-V supplies, the ADG5421/23 draw 130 A max. Specified from 40C to +125C, they are available in 10-lead MSOP packages and priced at $1.85 in 1000s.
