The SY89208V is a 3.3V/5V precision high-speed 2:1
multiplexer. It is functionally equivalent to the SY100EP58V
but in an ultra-small 8-lead MLF package that features a
70% smaller footprint. The signal-path inputs (Da and Db)
are single-ended PECL/ECL compatible, and can accept a
signal swing as low as 150mV. All I/O pins are 10k/100k EP
ECL/PECL compatible.
AC-performance is guaranteed over the industrial –40
°C
to +85
°C temperature range and 3.0V to 5.5V supply voltage
range. Maximum throughput (f
MAX) is guaranteed to be 3GHz
with a differential output swing
≥400mV. In addition, these
multiplexers are optimized for low-jitter applications. The
SY89208V is designed to operate in either ECL/PECL or
PECL/LVPECL mode. The SY89208V is internally
temperature compensated, thus is 100k EP ECL/PECL
compatible—I/O logic levels remain constant over
temperature.
The SY89208V is part of Micrel’s high-speed, Precision
Edge timing and distribution family. For applications that
require a differential 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.
