Description

[CREATE AND SAMPLE YOUR CUSTOM ZL30250 HERE](https://clockworks.microchip.com/microchip/design/inputZL) The ZL30250 is a flexible, high-performance, clock multiplier/generator. From any input clock frequency 9.72MHz to 1250MHz this device can produce frequency-locked output frequencies from 1Hz to 1035MHz and as many as 3 differential or 6 CMOS output clock signals. The ZL30250 has output jitter of 160fs RMS (12kHz to 20MHz). Automatic self-configuration from external EEPROM allows clock signals to be available immediately after power-up or reset.
