22 Cross Connect (XC) Block Functional Description
22.7.4 M23 DeMUX (Receive Path)
The M23 deMUX disassembles a DS3 into 7 DS2 signals. The M23 deMUX can cross connect DS2 data and clock
out to external pins and/or the test-pattern monitor as shown in
The M23 DS2 data and clock are connected to external I/O by programming the XC_PDATA[1—29]
page
select value from
1 to 7 to the external I/O pins LINETXDATA[1—29] and LINETXCLK[1—29] as selected by programming one of the
29 XC_PDATA[1—29] bytes.
For example, to connect the DS2 data and clock outputs from M23 deMUX 4 to the LINETXDATA[19] and
LINETXCLK[19] device pins, program the XC_PDATA19 byte in register XC_PIND_SRC10
ID = 000 (binary) and a channel ID = 20 (decimal) XC_PDATA19 = 00010100 (binary).
The demultiplexed DS2 may be connected to the test-pattern monitor (TPM) by programming the
XC2_TSOURCE_ID
of 1 to 7 corresponding to the deMUXed output to monitor. The TPM is limited to receiving unframed pseudoran-
dom data patterns.
