CDC5806PW
时钟发生器及支持产品 6 Output PLL Freq Gen
The CDC5806 is a clock generator which synthesizes video clocks, audio clocks, CPU clock, ASIC clock, USB clock, and a memory card clock from a 54-MHz system clock.
Three phase-locked loops PLLs are used to generate the different frequencies from the system clock. On-chip loop filters and internal feedback eliminate the need for external components.
Since the CDC5806 is based on PLL circuitry, it requires a stabilization time to achieve phase-lock of the PLLs. The PLL stabilization time begins after the reference clock input has a stable phase and frequency.
The device operates from a single 3.3-V supply voltage. The CDC5806 device is characterized for operation from 40°C to 85°C.
