FemtoClock® NG Differential-to-3.3V,
2.5V LVPECL Synthesizer
8N3PG10MBKI-161
Data Sheet
General 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 IDT’s 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 - 20MHz integration range).

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium
has been reached under these conditions.
NOTE 1: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 2: Refer to the Phase Noise plots.
