The CDCI6214device is an ultra-low power clock generator. The device selects between two independent referenceinputs to a phase-locked loop and generates up to four different frequencies on configurabledifferential output channels and also a copy of the reference clock on a LVCMOS outputchannel.
Each of the four output channels has a configurable integer divider. Together with the output muxes, this allows up to fivedifferent frequencies. Clock distribution dividers are reset in a deterministic way for clean clockgating and glitch-less update capability. Flexible power-down options allow to optimize the devicefor lowest power consumption in active and standby operation. Typically four 156.25-MHz LVDSoutputs consume 150 mW at 1.8 V. Typical RMS jitter of 386 fs for 100-MHz HCSL output enhancessystem margin for PCIe applications.
The CDCI6214 isconfigured using internal registers that are accessed by anI2C-compatible serial interface and internal EEPROM.
The CDCI6214enables high-performance clock trees from a single reference at ultra-low power with a smallfootprint. The factory- and user-programmable EEPROM make the CDCI6214 idealas easy-to-use, instant-on clocking solution with low power consumption.
