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.
Features
- High-performance clock RF-PLL:.
- Optimized for low phase noise: -157.7dBc/Hz (1MHz offset;
156.25MHz clock), design target.
- Integrated phase noise, RMS (12kHz.
- 20MHz): 73fs
(typical), design target.
- Dual-PLL architecture:.
- 1st-PLL stage with external VCXO for clock jitter attenuation.
- 2nd-PLL stage with internal FemtoClock NG PLL at
2500MHz.
- Four output banks with a total of 18 outputs, organized in:.
- Three clock banks with one i.
