Part Details

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, and G.825
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
Automatic and manual holdover and reference switchover, providing zero delay, hitless, or phase buildout operation
Programmable priority-based reference switching with manual, automatic revertive, and automatic nonrevertive modes supported
5 pairs of clock output pins with each pair useable as differential LVDS/HCSL/CML or as 2 single-ended outputs (1 Hz to 500 MHz)
2 differential or 4 single-ended input references
Crosspoint mux interconnects reference inputs to PLLs
Supports embedded (modulated) input/output clock signals
Fast DPLL locking modes
Provides internal capability to combine the low phase noise of a crystal resonator or crystal oscillator with the frequency stability and accuracy of a TCXO or OCXO
External EEPROM support for autonomous initialization
Single 1.8 V power supply operation with internal regulation
Built in temperature monitor/alarm and temperature compensation for enhanced zero delay performance
