4.2.3 Parallel Input in Data-Through Mode
When operating in Data-Through mode, see
Data-Through Mode on page 35
, the
GS1582 passes data from the parallel input bus to the serial output without
performing any encoding or scrambling. The input data bus width is controlled by
the setting of the 20bit/10bit pin.
4.2.4 Parallel Input Clock (PCLK)
The frequency of the PCLK input signal required by the GS1582 is determined by
the input data format.
Table 4-1
below lists the possible input signal formats and
their corresponding parallel clock rates. Note that the DVB-ASI input will only be in
10-bit format, when setting the 20bit/10bit pin LOW.
