{{eolnotice|none}}<br />
The ICE-D2E module is a LVTTL-to-differential ECL converter for use on an [[ICE-PIC6|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).<br />
<br />
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.<br />
<br />
== Series 2 Cards ==<br />
<br />
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.<br />
<br />
An internal clock is also available via software control: it is the onboard crystal 40MHz divided by an integer from 1 to 65535.<br />
<br />
* H3: Closed for 50 ohm termination<br />
* H4: Closed for DC-coupled clock input (0-5V)<br />
* Open for AC-coupled clock input (1Vpp)<br />
<br />
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.<br />
<br />
== Series 3 Cards ==<br />
<br />
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.<br />
