AD9520-3BCPZ

AD9520-3 is a 12 LVPECL/24 CMOS output clock generator with integrated 2GHz VCO. It provides a multioutput clock distribution function with sub picosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 1.72GHz to 2.25GHz. An external 3.3V/5V VCO/VCXO of upto 2.4GHz can also be used. This device's serial interface supports both SPI and I²C ports. An in-package EEPROM, which can be programmed through the serial interface, can store user-defined register settings for power-up and chip reset. It is used in applications such as low jitter, low phase noise clock distribution clock generation and translation for SONET, 10Ge, 10GFC, synchronous ethernet, OTU2/3/4, forward error correction (G.710), clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs, high performance wireless transceivers, ATE and high performance instrumentation, broadband infrastructures.

• Low phase noise, phase-locked loop (PLL), 1 differential or 2 single-ended reference inputs
• Glitch-free switchover between references, automatic recovery from holdover
• Digital or analog lock detect, selectable, optional zero delay operation
• Additive output jitter as low as 225fs rms, channel-to-channel skew grouped outputs is 16ps
• Automatic synchronization of all outputs on power-up, manual output synchronization available
• SPI- and I²C-compatible serial control port
• Non-volatile EEPROM stores configuration settings
• Accepts 16.62MHz to 33.3MHz crystal for reference input
• Operating temperature range from -40°C to +85°C
• Package style is 64-lead lead frame chip scale (LFCSP-VQ)
