Description

The 83PN161i is LVPECL output synthesizer designed for converting forward-error correction (FEC) clock frequencies in 10 GB Ethernet LAN/WAN transport applications. The device is optimized for an input frequency of 156.25MHz and supports four FEC rate conversions: 33/32, 255/237, 255/238 and 235/236. The conversion rate is pin-selectable and one of four rates are supported at a time. In the default configuration, an input clock of 156.25MHz is converted to an output clock of 168.8294492MHz (255/236). The device uses Renesas' fourth Generation of FemtoClock® NG technology to deliver low phase noise clocks combined with a low power consumption. The RMS phase jitter at 168.8294492MHz output frequency is 0.533ps (12kHz-20MHz integration range).
