CDC5806PWG4 [Texas Instruments]

The CDC5806 is a clock generator that uses three phase-locked loops (PLLs) to generate different frequencies from a 54-MHz system clock. It synthesizes video clocks, audio clocks, CPU clock, ASIC clock, USB clock, and memory card clock. On-chip loop filters and internal feedback eliminate the need for external components. The device operates from a single 3.3-V supply voltage and is characterized for operation from -40°C to 85°C. It features low jitter for clock distribution and low peak-to-peak period jitter (150ps max). The PLLs are powered down if no valid REF_IN clock (<5MHz) is detected or VDD is below 2V. Packaged in TSSOP(PW) 20-pin package.
