Function
Transmit Test Data Out Plus
Transmit Test Data Out Minus
PCM(+) and PCM(–) output signals which may be
used for diagnostic loopback. Data will continue to
be transmitted during AIS transmission via XDOP/
XDOM. The line code is determined by the bits
MODE.PMOD and MODE.CODE. Output sense is
selected via bit XC0.XTDS (after RESET: active
low). Timing specifications are equivalent to
XDOP/XDOM.
Receive Data Out
Received data which is sent to the system internal
highway with 4096 kbit/s or 2048 kbit/s (bit
MODE.IMOD). Clocking off data is done with the
falling edge of SCLK. The delay between the
beginning of time-slot 0 and the initial edge of
SCLK (after SYPQ goes active) is determined by
the values of Receive Time-slot Offset
RC1.RTO5 … 0 and Receive Clock-slot Offset
RC0.RCO2 … 0. Additionally for PCM 24, the
time-slot assignment between route and system
side is selected via bit MODE.CTM.
