描述 Description

The PL138-48 family is a high performance low-cost 1:4 outputs Differential LVPECL fanout buffer.The 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, PL138 family offers up to 1GHz of output operation with very low-power consumption, and lowest additive jitter of any comparable device. The Output Enable feature, when activated, allows the IC to consume less than 10μA of current.
