General Description

The ICS853S9252I is a 2.5V/3.3V ECL/LVPECL fanout buffer

designed for high-speed, low phase-noise wireless infrastructure

applications. The device fanouts a differential input signal to two

ECL/LVPECL outputs. Optimized for low additive phase-noise,

sub-100ps output rise and fall times, low output skew and

high-frequencies, the ICS853S9252I is an effective solution for

high-performance clock and data distribution applications, for

instance driving the reference clock inputs of ADC/DAC circuits.

Internal input termination, a bias voltage output (VREF) for

AC-coupling and small packaging (3.0mm x 3.0mm 16-lead VFQFN)

supports space-efficient board designs.

The ICS853S9252I operates from a full 2.5V or 3.3V power supply

and supports the industrial temperature range of -40°C to 85°C. The

extended temperature range also supports wireless infrastructure,

tele-communication and networking end equipment requirements.
