General Description

The SY58605U is a 2.5V, high-speed, fully differential

LVDS buffer optimized to provide less than 10ps

jitter. The SY58605U can process clock signals as fast

as 2GHz or data patterns up to 3.2Gbps.

The differential input includes Micrel’s unique, 3-pin

input termination architecture that interfaces to LVPECL,

LVDS or CML differential signals, (AC- or DC-coupled)

as small as 100mV (200mV

or termination resistor networks in the signal path. For

AC-coupled input interface applications, an integrated

voltage reference (V

The output is 325mV LVDS, with rise/fall times

guaranteed to be less than 100ps.

The SY58605U operates from a 2.5V ±5% supply and is

guaranteed over the full industrial temperature range

(–40°C to +85°C). For applications that require CML or

LVPECL outputs, consider Micrel’s SY58603U and

SY58604U, buffers with 400mV and 800mV output

swings respectively. The SY58605U is part of Micrel’s

high-speed, Precision Edge
