DESCRIPTION
The SY100EP56V is a high-speed, low-skew, fully
differential Dual PECL/ECL 2:1 multiplexer. This device is a
pin-for-pin, plug-in replacement to the MC10/100EP56DT.
Two separate 2:1 multiplexers (Channel 0 and Channel 1)
with dedicated select control pins (SEL0 and SEL1) are
implemented in a 20-pin TSSOP package. The signal-path
inputs (D0a, D0b and D1a, D1b) accept differential signals
as low as 150mV pk-pk. For applications that require
common select control for both channels A & B, a common
select pin (COM_SEL) is available. All I/O pins are 100k
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 500ps max (400 typ) propagation delay
is matched for all signal and logic select paths: D-to-Q_OUT,
SEL-to-Q_OUT, and COM_SEL-to-Q_OUT. Two V_BB output
reference pins (approx equal to V_CC –1.4V) are available
for AC–coupled or single-ended applications.
The SY100EP56V 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.
