differential PECL/ECL 4:1 multiplexer in a 20-pin TSSOP
package. This device is a pin-for-pin, plug-in replacement
to the MC10/100EP57DT. The signal-path inputs (D0:D3)
accept differential signals as low as 150mVpk-pk. All I/O
pins are 100K EP PECL/ECL logic compatible.
AC–performance is guaranteed over the industrial –40°C
to +85°C temperature range and 3.0V to 5.5V supply voltage
range. This device will operate in PECL/LVPECL or ECL/
LVECL mode. The SY100EP57 propagation delay is less
than 520ps, and the Select-to-valid output delay is less
than 575ps over temperature and voltage. For clock
applications, the high-speed design combined with an
extremely fast rise/fall time of less than 220ps produces a
toggle frequency as high as 3GHz (400mVpk-pk swing).
Two V
BB
output reference pins (approx equal to V
CC
–1.4V)
are available for AC–coupled or single-ended applications.
The SY100EP57V is part of Micrel’s high-speed, Precision
Edge timing and distribution family. For applications that
require a different I/O combination, consult the Micrel website
at www.micrel.com, and choose from a comprehensive
product line of high-speed, low skew fanout buffers,
translators, and clock dividers.

Function
Input Channels 0-3 PECL/ECL differential signal inputs. Multiplexing of these 4 differential inputs
is controlled by SEL0, SEL1. The signal inputs include internal 75kΩ pull-down resistors. Default
condition is LOW when left floating. The input signal should be terminated externally.
See “Termination” section
Negative Power Supply: For PECL/LVPECL applications, connect to Ground. Both V
EE
pins must
be connected together, externally on the PCB, for proper operation.
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
–1.4V, and tracks V
CC
1:1. Maximum sink/
source capability for each V
BB
reference pin is 0.50mA. For single ended PECL inputs, connect to
the unused input through a 50Ω resistor. Decouple the V
BB
pin with a 0.01µF capacitor. For PECL/
LVPECL inputs, the decoupling capacitor is connected to V
CC
, since PECL signals are referenced
to V
CC
. Leave floating if not used.
100KEP PECL/ECL compatible differential output. PECL/ECL termination is with a 50Ω
resistor to V
CC
–2V. Unused single-ended outputs must have a balanced load. For AC–coupled
applications, the output stage emitter follower must have a DC current path to ground.
See “Termination” section.
100KEP PECL/ECL compatible 4:1 MUX select control. See “MUX
Select Truth Table.”
Each pin
includes an internal 75kΩ pull-down resistor. Default condition when left floating is LOW.
Positive Power Supply. All V
CC
pins must be connected to the same power supply externally.
Bypass with 0.1µF//0.01µF low ESR capacitors.

1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions for extended
periods may affect device reliability.
2. Due to the limited drive capability, the V

reference should only be used for inputs from the same package device (i.e., do not sue for other
devices).
