By programming the Backplane or Local input channel delay registers, BCDR0-31 and LCDR0-15, users can
assign the Ch0 position to be located at any one of the channel boundaries in a frame. See Figure 9.
Figure 9 - Backplane and Local Input Channel Delay Timing Diagram (8 Mb/s)
For delays within channel boundaries, the input bit delay programming can be used. The use of Input Channel
Delay in combination with Input Bit Delay enables the Ch0 position to be placed anywhere within a frame to a
resolution of 1/4 of the bit period.
3.2 Input Bit Delay Programming (Backplane and Local Input Streams)
In addition to the Input Channel Delay programming, the Input Bit Delay programming feature provides users with
greater flexibility when designing switch matrices for high speed operation. The input bit delay may be programmed
on a per-stream basis to accommodate delays created on PCM highways. For all streams the delay is up to 7 3/4
bits with a resolution of 1/4 bit, for the selected data-rate.
See Figure 10 and Figure 11 for Input Bit Delay Timing at 16 Mb/s and 8 Mb/s data rates, respectively.
The Local input delay is defined by the Local Input Delay registers, LIDR0 to LIDR15, corresponding to the Local
data streams, LSTi0 to LSTi15, and the Backplane input delay is defined by the Backplane Input Delay registers,
BIDR0 to BIDR31, which correspond to the Backplane data streams, BSTi0 to BSTi31.
