Overview

Description

The 8N3PGDAMBKI-025 is a very versatile programmable LVPECL synthesizer that can be used for OTN/SONET to Ethernet or 10 GB 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 161.1328MHz is converted to 25MHz output. The device uses IDT's fourth generation FemtoClock NG technology to deliver low phase noise clocks combined with low power consumption. The RMS phase jitter at 25MHz output frequency is 0.66ps (12kHz - 5MHz integration range).
