Part Details
- Converts a low frequency input reference signal to a high frequency output signal
- Input frequencies from 6.6 MHz to 112.5 MHz
- Output frequencies up to 900 MHz
- Preset pin programmable frequency translation ratios
- Arbitrary frequency translation ratios via SPI port
- Accepts a crystal resonator and/or an external oscillator as a reference frequency source
- Secondary output (either integer-related to the primary output or a copy of the reference input)
- RMS jitter: <0.5 ps
- SPI-compatible, 3-wire programming interface
- Single supply (3.3 V)
- Very low power: <400 mW (under most conditions)
- Small package size (5 mm × 5 mm)
- On-chip VCO
The AD9552 is a fractional-N phase locked loop (PLL) based clock generator designed specifically to replace high frequency crystal oscillators and resonators. The device employs a sigma-delta (Σ-Δ) modulator (SDM) to accommodate fractional frequency synthesis. The user supplies an input reference signal by connecting a single-ended clock signal directly to the REF pin or by connecting a crystal resonator across the XTAL pins.
The AD9552 is pin programmable, providing one of 64 standard output frequencies based on one of eight common input frequencies. The device also has a 3-wire SPI interface, enabling the user to program custom input-to-output frequency ratios.
The AD9552 relies on an external capacitor to complete the loop filter of the PLL. The output is compatible with LVPECL, LVDS, or single-ended CMOS logic levels, although the AD9552 is implemented in a strictly CMOS process.
The AD9552 is specified to operate over the extended industrial temperature range of −40°C to +85°C.
APPLICATIONS
- Cost effective replacement of high frequency VCXO, OCXO, and SAW resonators
- Extremely flexible frequency translation with low jitter for SONET/SDH (including FEC) , 10 Gb Ethernet, Fibre Channel, and DRFI/DOCSIS
- High-definition video frequency translation
- Wireless infrastructure
- Test and measurement (including handheld devices)
