General Description

The SY89230U is a precision, low jitter 3.2GHz ÷3,

÷5

differential input includes Micrel’s unique, 3-pin

internal termination architecture that allows the input

to interface to any differential signal (AC- or DC-

coupled) as small as 100mV (200mV

level shifting or termination resistor networks in the

signal path. The outputs are 800mV, 100K-

compatible

guaranteed to be less than 200ps.

The SY89230U operates from a 2.5V ±5% or 3.3V

±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

Edge
