描述
The 83PN128I is a programmable LVPECL synthesizer that can be used for frequency conversions. The device uses Renesas' fourth generation FemtoClock® NG technology for optimal high clock frequency and low phase noise performance, combined with a low power consumption and high power supply noise rejection. Oscillator-level performance is maintained with Renesas' 4th Generation FemtoClock NG PLL technology, which delivers low rms phase jitter. The 83PN128I defaults to 161.132813MHz output using a 156.25MHz input with 2 select pins floating (pulled up with internal pullup resistors) but can also be set to 4 different frequency multiplier settings to support a wide variety of applications. The below table shows some of the more common application settings.
