ZL30253LDF1 Product Details

The ZL30252 and ZL30253LDF1 are flexible, high-performance, clock multiplier/jitter attenuator ICs. From any input clock frequency 1kHz to 1250MHz these devices can produce frequency-locked output frequencies from 1Hz to 1035MHz and as many as 3 differential or 6 CMOS output clock signals. Output jitter is typically 0.16 to 0.28ps RMS (12kHz to 20MHz). Automatic self-configuration from external (ZL30252) or internal (ZL30253) EEPROM allows clock signals to be available immediately after power-up or reset.ZL30252 and ZL30253LDF1 Product Preview ZL30252 and ZL30253LDF1 White Paper: Versatile, Easy-to-Use Solutions for a Wide Variety of Timing Challenges White Paper: Time and Frequency Synchronization in Broadcast VideoApplications/UsesClocks for Processors, NPUs, FPGAs, 10G CDRs, high-speed ADCs and DACs, PCIe interface devices, Ethernet switches and PHYsClock generation for wireless base stations, wireless backhaul, wired infrastructure, SONET/SDH, GE, 10G/40G/100G Ethernet, optical, storage, and broadcast video applicationsKey
