Dual, 1-TO-1
Differential-to-LVCMOS Translator/Buffer
83023I
Data Sheet
©2015 Integrated Device Technology, Inc December 14, 20151
GENERAL DESCRIPTION
The 83023I is a dual, 1-to-1 Differential-to-LVCMOS
Translator/Fanout Buffer. The differential inputs can accept most
differential signal types (LVDS, LVHSTL, LVPECL, SSTL, and
HCSL) and translate into two single-ended LVCMOS outputs.
The small 8-lead SOIC footprint makes this device ideal for use
in applications with limited board space.
Features
Two LVCMOS / LVTTL outputs
Two differential CLKx, nCLKx input pairs
CLK, nCLK pairs can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
Maximum output frequency: 350MHz (typical)
Output skew: 60ps (maximum)
Part-to-part skew: 500ps (maximum)
Additive phase jitter, RMS: 0.14ps (typical)
Small 8 lead SOIC package saves board space
3.3V operating supply
-40°C to 85°C ambient operating temperature
