SDA 525X-2
1
General Description
As its predecessors SDA 525x the SDA 525x-2 contains a slicer for VPS and TTX, an
accelerating acquisition hardware module, a display generator for “Level 1.5” TTX data,
and an 8 bit microcontroller running at 333 ns cycle time. The controller with dedicated
hardware guarantees flexibility, does most of the internal processing of TTX acquisition,
transfers data to/from the external memory interface and receives/transmits data via I
2
C
user interface. The block diagram shows the internal organization of the SDA 525x-2.
The slicer combined with dedicated hardware stores TTX data in a VBI buffer of
746 Byte. The microcontroller firmware performs all the acquisition tasks (hamming- and
parity-checks, page search and evaluation of header control bits) once per field.
This delta specification describes the differences of the SDA 525x-2 compared to the
SDA 525x as described in the preliminary data sheet 1997-09-01.
