Module E4 CMI |
701097 |
| |
Versatile Module allows CMI,
NRZ, or 4-bit parallel
nibble inputs and outputs |
| |
Description:
The Type J, CMI PCB module is a configurable, Coded Mark Inversion (CMI) encoder/decoder.
The unit can be configured to decode received single ended CMI input and
output recovered DATA and CLOCK either as NRZ or a parallel 4 bit data
nibble format with clock. When configured in the encoder mode, module accepts
either CMI, NRZ DATA and CLOCK or a 4 bit nibble format with clock to produce
a CMI encoded output data stream. The electrical format of all input and
output signals (except CMI) is differential ECL, PECL, LVDS, or RS422.
A test pattern generator can be selected by a front panel locking toggle
switch. The test generator is used to provide verification of the operation
of the output drivers in any mode and also allows the unit to function
as a signal source. |
