5.2. Isochronous Interface
This section explains the pin function of Isochronous interface.
Signal Name I/O Function
TSVALIDA I/O
I.O pin for indicating effective data period of TS packet (on port A)
‘H’ active signal
TSSYNCA I/O
Input/Output pin for indicating leading data of TS packet (on port A)
‘H’ active signal
TSCLKA I/O
On transmitting: sync clock input pin for input data of TS packet
On receiving : sync clock output pin for output data of TS packet
(switchable either 6.144MHz or 3.072MHz)
TSDA7 - 0 I/O I/O pin for TS packet data (on Port A)
TSCGMSA I
Serial input pin for CGMS and TSCH information (on port A)
Effective for 8 clocks since TSSYNCA input signal rising
SELIOA O
Output pin for switching I/O on port A
Outputs ‘L’ at transmitting and ‘H’at receiving
SELTSPA O Output pin for switching output device from port A
TSVALIDB I/O
I.O pin for indicating effective data period of TS packet (on port B)
‘H’ active signal
TSSYNCB I/O
Input/Output pin for indicating leading data of TS packet (on port B)
‘H’ active signal
TSCLKB I/O
On transmitting: sync clock input pin for input data of TS packet
On receiving
: sync clock output pin for output data of TS packet
(switchable either 6.144MHz or 3.072MHz)
TSDB7 - 0 I/O I/O pin for TS packet data (on port B)
TSCGMSB I
Serial input pin for CGMS and TSCH information (on port B)
Effective for 8 clocks since TSSYNCA input signal rising
SELIOB O
Output pin for switching I/O on port B
Outputs ‘L’ at transmitting and ‘H’at receiving
SELTSPB O Output pin for switching output device from port B
ICLK I Clock input pin from DV-IC
XILWRE O
Output pin for signal to be allowed accessing to Isochronous-FIFO
Asserted by completing reception of data for one source packet
‘L’ active signal
XIV I
Input signal for enable signal of Isochronous data
Output Isochronous-FIFO data to data output pin while this signal in
active.
Switch data synchronizing with rise edge of ICLK
XFP O
Output pin of time stamp trigger signal
‘L’ active signal
