説明
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 Renesas' 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).
