Effective January 1st 2022, ICE Enterprises will increase all product prices by 20%. Market forces, both rising component cost and increasing material lead time, are requiring the first price adjustment in company history. This price increase will allow ICE Enterprises to continue to design and manufacture quality electronic hardware as has been the case for over two decades. ICE Enterprises will honor all current price quotes and accept orders at existing pricing through the end of December 2021.

Differential ECL Ouput Module
Notice: End-of-Life has been announced for this product. Please see End-of-Life for details.

The ICE-D2E module is a LVTTL-to-differential ECL converter for use on an ICE-PIC card with a 16-bit digital I/O site. It converts the module site LVTTL levels to F100K differential ECL logical levels (compatible with standard Midas switch connections).

The 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.

Series 2 Cards

An external clock can be connected via SMB connector on the card edge and is jumpered to be DC-coupled LVTTL levels or an AC-coupled 1Vpp sine wave. The clock also has a jumper that applies a 50 ohm termination to ground.

An internal clock is also available via software control: it is the onboard crystal 40MHz divided by an integer from 1 to 65535.

  • H3: Closed for 50 ohm termination
  • H4: Closed for DC-coupled clock input (0-5V)
  • Open for AC-coupled clock input (1Vpp)

In standard configurations, the 40-pin connector will be cabled through the card edge connector to an 40-pin male IDC connector roughly 3-4 inches from outside of the chassis.

Series 3 Cards

There are three clock sources, all located on the motherboard, and are selectable via software control: the default clock is an external source connected to the motherboard SMB connector, usually a 1Vpp sine wave; the internal clock (INTCLK) is the onboard 40MHz crystal divided by an integer from 1 to 65535; the alternate clock (ALTCLK) is the socketed crystal X2 on the motherboard.

Status

EOL has been declared for this model: see End-of-Life for details. Please call for pricing and availability.
