Description
The 8P791208 is a low additive jitter 2:8 buffer with CMOS/
differential outputs The device takes one or two reference clocks,
selects between them using a pin selection, and generates up to
eight outputs that are the same as the reference frequency.
The 8P791208 supports two output banks, each with its own
power supply. All outputs in one bank would generate the same
output frequency, but each output can be individually controlled for
output type or output enable.
The device can operate over the -40°C to 85°C temperature
range.

Features
▪ Accepts input frequencies ranging from 1PPS (1Hz) to 700MHz
▪ Two differential inputs support LVPECL, LVDS, LVHSTL,
HCSL, or LVCMOS reference clocks
▪ Generates 8 differential or 16 LVCMOS outputs
▪ Outputs arranged in two banks of four outputs each
▪ Select pins control which input drives which of two output
banks
▪ Controlled by 3-level input pins that are 3.3V tolerant for all
core voltages
▪ Output type may be selected from LVPEC, LVDS or
2xLVCMOS
▪ Each bank supports a separate power supply of 3.3V, 2.5V,
or 1.8V
▪ LVCMOS outputs are limited to 125MHz maximum and support
swings of 3.3V, 2.5V, 1.8V, and 1.5V
▪ Individual output enables and output type selection supported
▪ Output noise floor of –158dBc/Hz at 156.25MHz
▪ Core voltage supply of 3.3V, 2.5V, or 1.8V
▪ –40°C to 85°C ambient operating temperature
▪ Lead-free (RoHS 6) QFN-32 (5 × 5mm) packaging
