Figure 7 - DVB Transport Packet Header Byte
After decoding the 188-byte MPEG packet, it is output on the MDO pins in 188 consecutive clock cycles.
Additionally when the TEI_En bit in the OP_CTRL_0 register (0x5A) is set high (default), the TEI bit of any uncorrectable
packet will automatically be set to ‘1’. If TEI_En bit is low then TEI bit will not be changed (but note that if this bit is already
1, for example, due to a channel error which has not been corrected, it will remain high at output).
*. Or 27.00 MHz clock
†. Cb = the total capacitance on either clock or data line in pF to maximum of 400pF.
CLK clock frequency (Primary)
Bus free time between a STOP and START
condition.
Hold time (repeated) START condition.
LOW period of CLK clock.
HIGH period of CLK clock.
Set-up time for a repeated START condition.
Data hold time (when input).
Data set-up time
Rise time of both CLK and DATA signals.
Fall time of both CLK and DATA signals, (100pF to
ground).
Set-up time for a STOP condition.
