SY10/100EP16U
2.5/3.3V Precision ECL Differential
Receiver/Driver
General Description
The SY10/100EP16U is a 2.5/3.3V, 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 and single-ended
applications, an integrated voltage reference (VBB) is
provided. Single-ended CLK input operation is limited
to VCC ≥ 3.0V in PECL mode, or VEE ≤ -3.0V. The VBB
pin should be used only as a bias for the
SY10/100EP16U since its current sink/source
capability is limited. Whenever used, the VBB 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 SY10/100EP16U operates from a 2.5V ±5% or
3.3V ±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.
