Description

The 8N3PG10MBKI-161 is a very versatile programmable LVPECL synthesizer that can be used for OTN/SONET to Ethernet or 10GB Ethernet to OTN/SONET rate conversions. The conversion rate is pin-selectable and one of the four rates is supported at a time. In the default configuration, an input clock of 156.25MHz is converted to 161.1328125MHz output (dithering off).

The device uses Renesas' fourth-generation FemtoClock® NG technology to deliver low phase noise clocks combined with low power consumption. The RMS phase jitter at 161.1328125MHz output frequency is 0.567ps (12kHz to 20MHz integration range).
