ULTRA-PRECISION 1:8 FANOUT

bUFFER WITH LVPECL OUTPUTS

AND INTERNAL TERMINATION

fully differential LVPECL 1:8 fanout buffer. The SY58032U

is optimized to provide eight identical output copies with

less than 20ps of skew and only 76fs

process clock signals as fast as 4GHz.

termination architecture that allows the SY58032U to directly

interface to LVPECL, CML, and LVDS differential signals

(AC- or DC-coupled) without any level-shifting or termination

resistor networks in the signal path. The result is a clean,

stub-free, low-jitter interface solution. The LVPECL (100k

temperature compensated) outputs feature 800mV typical

swing into 50ý loads, and provide an extremely fast rise/fall

time guaranteed to be less than 110ps.

3.3V ±10% supply and is guaranteed over the full industrial

temperature range (–40°C to +85°C). For applications that

require a higher high-speed 1:8 fanout buffer, consider the

SY58031U or SY58033U. The SY58032U is part of Micrel’s

high-speed, Precision Edge
