CDC7005
description
The CDC7005 is a high-performance, low-phase noise, and low-skew clock synthesizer and jitter cleaner that synchronizes the voltage controlled crystal oscillator (VCXO) frequency to the reference clock. The programmable predividers M and N give a high flexibility to the frequency ratio

NPD of the reference clock to VCXO: VCXO_IN/
REF_IN = (Nx P)/M. The VCXO_IN clock operates up to 800 MHz. Through the selection of external
VCXO and loop filter ponents, the PLL loop bandwidth and damping factor can be adjusted to meet different system requirements. Each of the five differential LVPECL outputs are programmable by the serial peripheral interface (SPI). The SPI allows individual control of frequency and enable/disable state of each output. The device operates in 3.3-V environment. The built-in latches...
