ECL/LVPECL Clock Generator
87332I-01
DATA SHEET
87332AMI-01 REVISION C 2/12/15 1 ©2015 Integrated Device Technology, Inc.
GENERAL DESCRIPTION
The 87332I-01 is a high performance ÷2 Differential-to-2.5V/3.3V
ECL/LVPECL Clock Generator. The CLK, nCLK pair can accept
most standard differential input levels The 87332I-01 is characterized
to operate from either a 2.5V or a 3.3V power supply. Guaranteed
output and part-to-part skew characteristics make the 87332I-01
ideal for those clock distribution applications demanding well defi ned
performance and repeatability.
FEATURES
• One ÷2 differential 2.5V/3.3V LVPECL / ECL output
• One CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
• Maximum output frequency: 500MHz
• Maximum input frequency: 1GHz
• Translates any single ended input signal to 3.3V LVPECL
levels with resistor bias on nCLK input
• Part-to-part skew: 400ps (maximum)
• Propagation delay: 1.6ns (maximum)
• LVPECL mode operating voltage supply range:
V
CC
= 2.375V to 3.8V, V
EE
= 0V
• ECL mode operating voltage supply range:
V
CC
= 0V, V
EE
= -2.375V to -3.8V
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
