AD9545 Product details

Description

The AD9545 supports existing and emerging International Telecommunications Union (ITU) standards for the delivery of frequency, phase, and time of day over service provider packet networks, including ITU-G.8262, ITU-T G.812, ITU-T G.813, ITU-T G.823, ITU-T G.824, ITU-T G.825, and ITU-T G.8273.2.

Features

Dual DPLL synchronizes 1 Hz to 750 MHz physical layer clocks, providing frequency translation with jitter cleaning of noisy references Complies with ITU-T G.8262 and Telcordia GR-253 Supports Telcordia GR-1244, ITU-T G.812, ITU-T G.813, ITU-T G.823, ITU-T G.824, ITU-T G.825, and ITU-T G.8273.2 Continuous frequency monitoring and reference validation for frequency deviation as low as 50 ppb (5 × 10.
8) Both DPLLs feature a 24-bit fractional divider with 24-bit programmable modulus Programm.
