MAIN FEATURES

•

Single chip PLL:

• Features 0.5 mHz to 560 Hz bandwidth

• Provides node clock for ITU-T G.8261/G.8262 Synchronous

• Exceeds GR-253-CORE (OC-192) and ITU-T G.813 (STM-64)

• Provides node clocks for Cellular and WLL base-station (GSM

• Provides clocks for DSL access concentrators (DSLAM), espe-

• Provides clocks for 1 Gigabit and 10 Gigabit Ethernet application

• Supports clock generation for IEEE-1588 applications

Provides an integrated single-chip solution for Synchronous Equip-

ment Timing Source, including Stratum 3, Stratum 4E, Stratum 4,

SMC, EEC-Option 1 and EEC-Option 2 Clocks

Supports 1PPS input and output

Employs PLL architecture to feature excellent jitter performance

and minimize the number of external components

Integrates T4 DPLL and T0 DPLL; T4 DPLL locks independently or

locks to T0 DPLL

Supports programmable DPLL bandwidth (0.5 mHz to 560 Hz in 19

steps) and damping factor (1.2 to 20 in 5 steps)

Supports 1.1X10

ppm instantaneous holdover accuracy

Supports hitless reference switching to minimize phase transients

on T0 DPLL output to be no more than 0.61 ns

Supports programmable input-to-output phase offset adjustment

Limits the phase and frequency offset of the outputs

Provides OUT1~OUT7 output clocks whose frequency cover from

1PPS to 644.53125 MHz

• Includes 25 MHz, 125 MHz and 156.25 MHz for CMOS outputs

• Includes 25.78125 MHz, 128.90625 MHz and 161.1328125 MHz

• Includes 25 MHz, 125 MHz, 156.25 MHz, 312.5 MHz and 625

• Includes 25.78125 MHz, 128.90625 MHz, 161.1328125 MHz,

Provides OUT8 for composite clocks and OUT9 for 1.544 MHz/
