SY89230U
3.2GHz Precision, LVPECL Г 3, Г 5 Clock
Divider General Description
The SY89230U is a precision, low jitter 3.2GHz Г 3,
Г 5 clock divider with a LVPECL output. The
differential input includes Micrel’s unique, 3-pin
internal termination architecture that allows the input
to interface to any differential signal (AC-or DCcoupled) as small as 100mV (200mVPP) without any
level shifting or termination resistor networks in the
signal path. The outputs are 800mV, 100Kcompatible LVPECL with fast rise/fall times
guaranteed to be less than 200ps.
The SY89230U operates from a 2.5V В±5% or 3.3V
В±10% supply and is guaranteed over the full
industrial temperature range of –40°C to +85°C. The
SY89230U is part of Micrel’s high-speed, Precision
В®
Edge product line.
