AD9523-1

Low Jitter Clock Generator with 14 LVPECL/LVDS/HSTL/29 LVCMOS Outputs
Manufactured by:

Product Details

The AD9523-1 provides a low power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO with two VCO dividers. The on-chip VCO tunes from 2.94 GHz to 3.1 GHz.

The AD9523-1 is defined to support the clock requirements for long term evolution (LTE) and multicarrier GSM base station designs. It relies on an external VCXO to provide the reference jitter cleanup to achieve the restrictive low phase noise require-ments necessary for acceptable data converter SNR performance.

The input receivers, oscillator, and zero delay receiver provide both single-ended and differential operation. When connected to a recovered system reference clock and a VCXO, the device generates 14 low noise outputs with a range of 1 MHz to 1 GHz, and one dedicated buffered output from the input PLL (PLL1). The frequency and phase of one clock output relative to another clock output can be varied by means of a divider phase select function that serves as a jitter-free, coarse timing adjustment in increments that are equal to half the period of the signal coming out of the VCO.

An in-package EEPROM can be programmed through the serial interface to store user-defined register settings for power-up and chip reset.

Product Details

The AD-FMCDAQ2-EBZ module is comprised of the AD9680 dual, 14-bit, 1.0 GSPS, JESD204B ADC, the AD9144 quad, 16-bit, 2.8 GSPS, JESD204B DAC, the AD9523-1 14-output, 1GHz clock, and power management components. It is clocked by an internally generated carrier platform via the FMC connector, comprising a completely self-contained data acquisition and signal synthesis prototyping platform. In an FMC footprint (84 mm × 69 mm), the module’s combination of wideband data conversion, clocking, and power closely approximates real-world hardware and software for system prototyping and design, with no compromise in signal chain performance.

Applications

  • Electronic test and measurement equipment
  • General-purpose software radios
  • Radar systems
  • Ultra wideband satellite receivers
  • Point-to-point communication systems
