DESCRIPTION
The SY100EP15V is a high-speed, low-skew, PECL/ECL
1:4 precision fanout buffer with a 2:1 mux front end in a
small 16-pin TSSOP package. The 2:1 mux input accepts a
single-ended PECL/ECL source (CLK1) and a differential
PECL/ECL/HSTL source (CLK0). 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 3.3V to 5V supply voltage.
This device will operate in PECL/LVPECL or ECL/LVECL
mode. For clock applications, the high-speed design
combined with an extremely fast rise/fall time of less than
225ps produces a toggle frequency as high as 2.5GHz
(~400mV_PP swing).
A V_BB output reference pin is available for AC–coupled
and single-ended input applications. In addition, a
synchronous output enable function is provided.
The SY100EP15V is part of Micrel’s high-speed, precision
edge timing and distribution family. For applications that
require a different I/O combination, consult Micrel's website
at www.micrel.com, and choose from a comprehensive
product line of high-speed, low-skew fanout buffers,
translators, and clock dividers.
