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.

Pin Function
ECL Inputs. The D input has an internal 75kΩ pull-down resistor and the /D has an internal
37.5kΩ pull-up and a 75kΩ pull-down resistor.
ECL Outputs. Terminate with 50Ω to V
CC
-2V. See “Output Interface Applications” section for
more details.
Reference Output Voltage: This reference is typically used to bias the unused inverting input
for single-ended input applications, or as the termination point for AC-coupled differential
input applications. V
BB
reference value is approximately V
CC
- 1.42V, and tracks V
CC
1:1.
Maximum sink/source capability for V
BB
is 0.50mA. For single ended inputs, connect to the
unused input through a 50Ω resistor. Decouple the V
BB
pin with a 0.01µF capacitor to V
CC.
Positive Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitors as close to the V
CC
pin as possible.
Negative Power Supply: V
EE
and exposed pad must be tied to the most negative supply.
Exposed pad is available for 8-pin MLF
®
package only.
