Product specification
MPEG-2 video and MPEG-audio/AC-3
audio encoder with multiplexer
SAA6752HS
7.8
MPEG stream output port
7.8.1
G
ENERAL
The MPEG stream output port connects the SAA6752HS
multiplexer output to the outside world. The parallel
interface performs a parallel output transition of audio and
video data to an externally connected device and supports
3-bus protocol modes.
7.8.2
O
UTPUT PORT CONFIGURATION OPTIONS
The following configuration options can be selected from
the host:
OUTPUT PROTOCOL. Three output protocols can be
selected: DIO slave mode, DIO master mode and DEBI
slave mode and associated signalling pin polarities.
OUTPUT DISABLE. Output can be set to
high-impedance if the SAA6752HS is not used in
application.
7.8.3
D
ATA OUTPUT FORMAT
The data to be transmitted have a width of 8 bits in all
modes. The data output port supports DIO and DEBI bus
protocols. The bus protocol mode is set via an I
2
C-bus
controlled register. The DEBI protocol provides only a
transmission of 8-bit data block transfer without address
decoding.

ROTOCOL DESCRIPTION

Output port definitions
7.8.4.1
DIO master mode
The PDIOCLK clock for the DIO interface is derived from
the system clock by a division of the 27 MHz clock by 3 or
by 4, generating a data output clocked at 9 or 6.75 MHz.
A PDOVAL signal indicates whether current data at the
output is valid. If the output buffer is empty the PDOVAL
signal will stay LOW. The number of valid pulses indicate
the real number of data transmissions. The signal
PDOSYNC in conjunction with PDOVAL indicates the first
byte of a transport stream packet.

DESCRIPTION

I
Request from external system if
interface is in DEBI slave mode.
I/O Output clock to the external system if
interface is set to DIO master mode.
Input clock to the SAA6752HS if
interface is set to DIO slave mode.
O
output data (8-bit parallel)
O
Indicates a first byte of a data packet
(for transport streams in DIO mode).
O
Indicates when an audio packet is
output (for transport stream).
O
Indicates whether currently sent data
is valid.
