Data Sheet
Quad Input, 10-Output, Dual DPLL/IEEE 1588 Synchronizer and Jitter Cleaner AD9543
FEATURES
Dual DPLL synchronizes 2 kHz 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, G.813, G.823,
G.824, G.825, and G.8273.2 Continuous frequency monitoring and reference validation
for frequency deviation as low as 50 ppb Both DPLLs feature a 24-bit fractional divider with 24-bit
programmable modulus Programmable digital loop filter bandwidth: 10−4 Hz to 1850 Hz Two independent, programmable auxiliary NCOs (1 Hz to
65,535 Hz, resolution < 1.
