Type Description
RxCLK1
I
Receive Clock 1
The clock input pin used for sampling the data on
RxD1 The MUNICH128X supports the following PCM
clock rates, programmed via the MODE1 register:
T1: 1.536 MHz, 1.544 MHz, 3.088 MHz, 6.176 MHz;
E1: 2.048 MHz, 4.096 MHz, 8.192 MHz.
RxD1
I
Receive Data 1
The data input pin which is sampled using RxCLK1.
RSP1
I
Receive Synchronization Pulse 1
The input pin used for Rx PCM frame synchronization;
the synchronization pulse marks the firstbit in the
PCM frame.
TxCLK1
I
Transmit Clock 1
The clock input used for clocking out the data on
TxD1. In most applications, the signal that drives this
pin is externally connected to RxCLK1.
TxD1
O
Transmit Data 1
Provides the data which is clocked out of the
MUNICH128X by TxCLK1; data is push-pull for active
bits in the PCM frame and TRISTATE
for inactive
bits.
TSP1
I
Transmit Synchronization Pulse 1
The input pin used for Tx PCM frame synchronization;
the synchronization pulse marks the lastbit in the
PCM frame.
TxDEN1
O
Transmit Data Enable 1
An active low output signal which specifies data on the
TxD1 output pin is valid.
