PM5343 STXC
SONET/SDH TRANSPORT OVERHEAD TRANSCEIVER
Pin Name Pin Type Pin Function
No.
INTB
Output
99 The active low, open drain interrupt (INTB)
signal is set when an event is detected on one
of the STXC maskable interrupt sources.
A[6]
Input
114 The address bus (A[6:0]) selects specific
A[5]
115 registers during accesses.

ALE
Input
121 The address latch enable (ALE) signal latches
the address bus (A[6:0]) when low. This allows
the STXC to be interfaced to a multiplexed
address/data bus. The address latches are
transparent when ALE is high. The ALE input
has an integral pull up resistor.
MBEB
Input
122 The active low Motorola bus enable (MBEB)
signal configures the STXC for Motorola bus
mode where the RDB/E signal functions as E,
and the WRB/RWB signal functions as RWB.
When MBEB is high, the STXC is configured
for Intel bus mode where the RDB/E signal
functions as RDB. The MBEB input has an
integral pull up resistor.
CSB
Input
111 The active low chip select (CSB) signal is
asserted during all register accesses.
