AD9520-4BCPZ

AD9520-4 is a 12 LVPECL/24 CMOS output clock generator. 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 1.4GHz to 1.8GHz. An external 3.3V/5V VCO/VCXO of up to 2.4GHz can also be used. This 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 features 12 LVPECL outputs in four groups. Any of the 1.6GHz LVPECL outputs can be reconfigured as two 250MHz CMOS outputs. Application includes low jitter, low phase noise clock distribution, 10/40/100 Gb/sec networking line cards, including SONET, 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.

• Low phase noise, phase-locked loop (PLL), reference monitoring capability
• Reference monitoring capability, additive output jitter as low as 225fs rms
• Automatic/manual reference holdover and reference switchover modes, with revertive switching
• Glitch-free switchover between references, automatic recovery from holdover
• Automatic synchronization of all outputs on power-up
• Non-volatile EEPROM stores configuration settings
• VS range from 3.135 to 3.465V (3.3V ± 5%, VS=VS-DRV= 3.3V ± 5%, VS ≤ VCP ≤ 5.25V, TA=25°C, typ)
• Frequency range from 1400 to 1800MHz (VS=VS-DRV= 3.3V ± 5%, VS ≤ VCP ≤ 5.25V, TA=25°C, typ)
• Typical frequency pushing is 1MHz/V (VS=VS-DRV= 3.3V ± 5%, VS ≤ VCP ≤ 5.25V, TA=25°C, typ)
• 64-lead LFCSP-VQ package, temperature range from -40°C to +85°C
