Laser Distance Measurement Applications
The CDCEL824 is a modular PLL-based low-cost, high-performance, programmable clock synthesizer, multiplier, and divider. It generates up to four output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 201MHz, using up to two independent configurable PLLs.
The CDCEL824 has a separate output supply pins, VDDOUT, which are 1.8V.
The input accepts an external crystal or LVCMOS clock signal. In case of a crystal input, an on-chip load capacitor is adequate for most applications. The value of the load capacitor is programmable from 0pF to 20pF.
