8V19N478
8V19N478 is Jitter Attenuator and Clock Synthesizer manufactured by Renesas.
FemtoClock® NG Jitter Attenuator and Clock Synthesizer
Description
The 8V19N478 is a fully integrated FemtoClock NG jitter attenuator and clock synthesizer designed as a high-performance clock solution for conditioning and frequency/phase management of 10/40/100/400 Gigabit-Ethernet line cards. The device is optimized to deliver excellent phase noise performance as required to drive physical layer devices, and provides the clean clock frequencies of 625MHz, 500MHz, 312.5MHz, 250MHz, 156.25MHz, and 125MHz.
A two-stage PLL architecture supports both jitter attenuation and frequency multiplication. The first stage PLL is the jitter attenuator, and uses an external VCXO...
