General Description

The SY100EP16V is a 3.3/5V, high-speed, fully

differential ECL Receiver/Driver that can process

clock signals as fast as 3GHz or data patterns up to

2.5Gbps.

The differential input includes an internal 75k

Ω pull-

down resistor on both the true and complement inputs

and a 37.5k

Ω pull-up resistor in the complement input

only. For AC-coupled input interface applications, an

for either single-ended use or for DC biasing when AC

only as a bias for the SY100EP16V since its current

sink/source capability is limited. Whenever used, the

supply voltage. The output is 800mV ECL, with fast

rise/fall times guaranteed to be less than 200ps.

When the inputs are left open, the internal input

clamps will force the Q output low.

The SY100EP16V operates from a 3.3V or 5V ±10%

supply and is guaranteed over the full industrial

temperature

range

(–40°C

to

+85°C).The

SY100EP16V is part of Micrel’s high-speed, Precision

Edge
