E2D-r5 Diagram

The ICE-E2D module is a differential ECL-to-LVTTL converter for use on an ICE-PIC card with a 16-bit digital I/O site. It converts F100K differential ECL logical levels (compatible with standard Midas switch connections) into LVTTL levels.

The module supports a number of termination options. The center of the differential input resistor pair may be:

  1. Left open
  2. Connected directly to Gnd
  3. Connected to Gnd through a capacitor

The default configuration for SDN connections is option 3, with 50 ohm resistors and 0.1uF capacitors. For direct ribbon cable connections, option 1, with a pair of 50 ohm resistors, is typically used. Options 1 and 2 must be special ordered.

The input/output connector is a 40-pin ribbon cable with data bit 0 on pins 1 and 40, bit 1 on pins 2 and 39, etc., bit 15 on pins 16 and 25, and clock on pins 20 and 21.
