2.2.3 Data Burst Transfers
The data burst timing provides the full data rate of 148.5 MByte/s. VALID is asserted when the first data is
valid at PDATA[35.0]. With every rising edge of RDCLK the PDATA inputs are registered, serialized and
transmitted. VALID can remain asserted as long as new data are available.
In the timing diagram PARGEN is de-asserted and the application delivers the PARITY bit synchronously
to the data word.
Note : For timings with assertion of FLAGI, please see section 3.2.5
10/2003 - rev. 2.0

*A dislock pulse generates an internal transmitter reset. Therefore both signals have to be at least
50us at high state before transmitter is operational.
