描述 Description

The ZL30159 single PLL rate converter is part of Microchip's ClockCenter platform and can synchronize to any clock rate from 1 Hz (1pps) to 750 MHz. The conversion from 1pps is especially useful for GPS clock generation to 25MHz or 156.25MHz. The ZL30159 includes a high precision synthesizer that can generate any clock rate from 1Hz to 177.5 MHz with jitter below 1ps.
