General Description

The 83021I is a 1-to-1 Differential-to-LVCMOS/ LVTTL Translator

and a member of the family of High Performance Clock Solutions

from IDT. The differential input is highly flexible and can accept the

following input types: LVPECL, LVDS, LVHSTL, SSTL, and HCSL.

The small 8-lead SOIC footprint makes this device ideal for use in

applications with limited board space.

Features

• One LVCMOS/LVTTL output

• Differential CLK/nCLK input pair

• CLK/nCLK pair can accept the following differential

input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

• Output frequency: 350MHz (typical)

• Part-to-part skew: 500ps (maximum)

• Additive phase jitter, RMS: 0.21ps (typical), 3.3V output

• Full 3.3V and 2.5V operating supply

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