SY58030U - Micrel Semiconductor

SY58030U ULTRA PRECISION DIFFERENTIAL LVPECL 4:1 MUX

The SY58030U is a 2.5V/3.3V precision, high-speed, 4:1 differential multiplexer with 400mV LVPECL outputs, capable of handling clocks up to 7GHz and data streams up to 10.7Gbps. In addition, a 1:2 fanout buffer provides two copies of the selected input. The differential input includes Micrel’s unique, 3-pin input termination architecture that allows customer.

Features

United States Patent No. RE44,134
■ Selects 1 of 4 differential inputs
■ Provides two copies of the selected input
■ Guaranteed AC performance over temperature and voltage:
• DC-to- > 10.7Gbps data rate throughput
• < 340ps IN-to-Out tpd
• < 80ps tr / tf times
■ Ultra low-jitter design:
