2.5 V, 3.3 V Differential LVPECL Clock

Divider and Fanout Buffer

8T73S208B-01

Datasheet

General Description

Features

The 8T73S208B-01 is a high-performance differential LVPECL clock

divider and fanout buffer. The device is designed for the frequency

division and signal fanout of high-frequency, low phase-noise clocks.

The 8T73S208B-01 is characterized to operate from a 2.5V and 3.3V

power supply. Guaranteed output-to-output and part-to-part skew

characteristics make the 8T73S208B-01 ideal for those clock

distribution applications demanding well-defined performance and

repeatability. The integrated input termination resistors make

interfacing to the reference source easy and reduce passive

component count. Each output can be individually enabled or

disabled in the high-impedance state controlled by a I²C register. On

power-up, all outputs are disabled.

• One differential input reference clock

• Differential pair can accept the following differential input

levels: LVDS, LVPECL, CML

• Integrated input termination resistors

• Eight LVPECL outputs

• Selectable clock frequency division of ÷1, ÷2, ÷4 and ÷8

• Maximum input clock frequency: 1GHz

• LVCMOS interface levels for the control inputs

• Individual output enable/disabled by I²C interface

• Power-up state: all outputs disabled

• Output skew: 60ps (maximum)

• Output rise/fall times: 350ps (maximum)

• Low additive phase jitter, RMS: 182fs (typical)

• Full 2.5V and 3.3V supply voltages

• Lead-free (RoHS 6) 32-Lead VFQFN packaging

• -40°C to 85°C ambient operating temperature
