Overview

MC100EP196B 3.
3 V ECL Programmable Delay Chip With FTUNE Descriptions The MC100EP196B is a Programmable Delay Chip (PDC) designed primarily for clock deskewing and timing adjustment.
It provides variable delay of a differential NECL/PECL input transition.
It has similar architecture to the EP195 with the added feature of further tunability in delay using the FTUNE pin.
The FTUNE input takes an analog voltage from VCC to VEE to fine tune the output delay from 0 to 60 ps.
The delay section consists of a programmable matrix of gates and multiplexers as shown in the logic diagram, Figure 3.
The delay increment of the EP196B has a digitally selectable resolution of about 10 ps and a net range of up to 10.
4 ns.
The required delay is selected by the 10 data select inputs D[9:0] values and controlled by the LEN (Pin 10).
A LOW level on LEN allows a transparent LOAD mode of real time delay values by D[9:0].
A LOW to HIGH transition on LEN will LOCK and HOLD current values present against any ...
