General Description

The PL138-48 is a high performance low-cost 1:4

outputs differential LVPECL fanout buffer.

Microchip’s family of differential LVPECL buffers are

designed to operate from a single power supply of 2.5V

±5% or 3.3V ±10%. The differential input pairs are

designed to accept most standard input signal levels,

using an appropriate resistor bias network, and

produce a high quality set of outputs with the lowest

possible skew on the outputs, which is guaranteed for

part-to-part or lot-to-lot skew.

Designed to fit in a small form-factor package, the

PL138-48 offers up to 800 MHz of output operation with

very low-power consumption and lowest additive jitter

of any comparable device.
