Data Sheet
3.2.2
The MPEGEN bit in the CONFIG register must be set low to enable the MPEG data. The maximum movement in the packet
synchronization byte position is limited to ±1 output clock period. MOCLK will be a continuously running clock once symbol
lock has been achieved, and is derived from the symbol clock. MOCLK is shown in Figure 8 with MOCLKINV = ‘1’, the default
state, see register 0x50.
All output data and signals (MDO[7:0], MOSTRT, MOVAL & BKERR) change on the negative edge of MOCLK (MOCLKINV = 1)
to present stable data and signals on the positive edge of the clock.
A complete packet is output on MDO[7:0] on 188 consecutive clocks and the MDO[7:0] pins will remain low during the
inter-packet gaps. MOSTRT goes high for the first byte clock of a packet. MOVAL goes high on the first byte of a packet
and remains high until the last byte has been clocked out. BKERR goes low on the first byte of a packet where uncor-
rectable bytes are detected and will remain low until the last byte has been clocked out.
