Description

830S21I 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

• Maximum output frequency: 350MHz

• Part-to-part skew: 525ps (maximum)

• Additive Phase jitter, RMS: 0.11ps (typical)

• Small 8 lead SOIC package saves board space

• Full 3.3V and 2.5V operating supply

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

• Available in lead-free (RoHS 6) package

• Designed for the fanout of 1PPS signals
