FUNCTION |
|
Sources |
Program selectable, one of
four inputs: three NRZ-L
Data and 0º Clock inputs; one internal Test Pattern input. |
|
Impedance |
50 Ohm input impedance,
TTL compatible. |
|
Bit Rate |
Up to 32M bits per second. |
|
Polarity |
Programmable, automatic
polarity correction. |
|
Word Length |
Programmable, 1 to 32 bit
word length for each input. |
|
Word Orientation |
Programmable, MSB/LSB
orientation for each input word. |
|
Parity |
Selectable leading,
trailing, or no parity checking for each word. |
|
SYNCHRONIZATION |
|
Mainframe Sync |
Mainframe synchronization provides for
programmable synch pattern and mask, complement pattern recognition,
and variable length frame decommutation. The pattern may be up to 64
bits in length. |
|
Subframe Sync |
Six independent synchronizers are capable
of decommutating sub-frames within subframes. Subframes synchronize to
fixed recycle patterns, complement frame sync patterns, and various ID
patterns. Both recycle and ID patterns may be assembled from multiple
word locations. Recycle patterns may be up to 32 bits long. |
|
ID Sync |
Two types of ID synchronization are
supported: JAM patterns of arbitrary values, and incrementing or
decrementing frame counters with limit checking.
ID sync words may be up to 16 bits in length. |
|
Sync Strategy |
Programmable Search-Check-Lock sync
strategy, bit error tolerance,and bit slip window provide reliable
frame synchronization. |
|
Asynchronous Formats |
Subframe synchronizer may be programmed
to decommutate embedded formats having unique frame sync patterns and
format structures. |
|
Format Switching |
16
testable flags store the results of bit or word comparisons on the
input stream to control decommutation . |
|
OUTPUT |
|
Data |
Data is available to the host computers
as memory-mapped frame buffers or CVT or as a data stream selectably
transferred by PCI bus DMA or HOTLink™.
Data is 32 bits with programmable MSB/LSB output word justification,
sign extension or zero insertion for LSB output. |
|
ID Tag |
Unique ID tags may be assigned to each
word: a total of 131,072 tags is possible. The 32-bit ID word includes
ID tag, status, and microsecond time. |
|
Frame Quality |
Frame quality word is generated
containing bit sync and frame sync status for downstream data
validation. |
|
2 Serial PCM Outputs |
Two programmably controlled RS-422
compatible
serial output channels are available. |
