RxCLK3
I
Receive Clock 3
The clock input pin used for sampling the data on
RxD3. 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.
85
RxD3
I
Receive Data 3
The data input pin which is sampled using RxCLK3.
86
RSP3
I
Receive Synchronization Pulse 3
The input pin used for Rx PCM frame synchronization;
the synchronization pulse marks the
first bit in the
PCM frame.
81
TxCLK3
I
Transmit Clock 3
The clock input used for clocking out the data on
TxD3. In most applications, the signal that drives this
pin is externally connected to RxCLK3.
83
TxD3
O
Transmit Data 3
Provides the data which is clocked out of the
MUNICH128X by TxCLK3; data is push-pull for active
bits in the PCM frame and TRISTATE for inactive
bits.
82
TSP3
I
Transmit Synchronization Pulse 3
The input pin used for Tx PCM frame synchronization;
the synch. pulse marks the
last bit in the PCM frame.
84
TxDEN3
O
Transmit Data Enable 3
An active low output signal which specifies data on the
TxD3 output pin is valid.
