SY100EP16V
3.3V/5V Precision ECL Differential
Receiver/Driver
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 75kΩ pull-
down resistor on both the true and complement inputs
and a 37.5kΩ pull-up resistor in the complement input
only. For AC-coupled input interface applications, an
integrated voltage reference (V_BB) is provided to bias
for either single-ended use or for DC biasing when AC
coupling to the device. The V_BB pin should be used
only as a bias for the SY100EP16V since its current
sink/source capability is limited. Whenever used, the
V_BB pin should be bypassed to the most positive
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^® product line.
