813N252DI-02

Jitter Attenuator & FemtoClock NG® Multiplier 813N252DI-02 DATA SHEET General Description Features The 813N252DI-02 device uses IDT's fourth generation FemtoClock® NG technology for optimal high clock frequency and low phase noise performance, combined with a low power consumption and high power supply noise rejection. The 813N252DI-02 is a PLL based synchronous multiplier that is optimized for PDH or SONET to Ethernet clock jitter attenuation and frequency translation. The813N252DI-02 is a fully integrated Phase Locked loop utilizing a FemtoClock NG Digital VCXO that provides the low jitter, high frequency SONET/PDH output clock that easily meets OC-48 jitter requirements. This VCXO technology simplifies PLL design by replacing the pullable crystal requirement of analog VCXOs with a fixed 27MHz generator crystal. Jitter attenuation down to 10Hz is provided by an external loop filter. Pre-divider and output divider multiplication ratios are selected using device selection control...
