SDA525X-2General Description
As its predecessors SDA525x the SDA525x-2 contains a slicer for VPS and TTX, an
accelerating acquisition hardware module, a display generator for “Level 1.5” TTX data,
and an 8bit microcontroller running at 333ns 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 I2C
user interface. The block diagram shows the internal organization of the SDA525x-2.
The slicer combined with dedicated hardware stores TTX data in a VBI buffer of
746Byte. 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 SDA525x-2 compared to the
SDA 525x as described in the preliminary data sheet 1997-09-01.Complete Feature List Including New Features
New features compared to SDA 525x-Specification, version 06/96 are printed in italic
and bold. As described in the errata sheet 03/97, release 1.0, the newer versions of the
SDA 525x and the SDA 525x-2 will not have a serial port (UART) any more.Acquisition:Feature selection via special function registerSimultaneous reception of TTX, VPS, and WSSFixed framing code for VPS and TTXAcquisition during VBIDirect access to VBI RAM bufferAcquisition of packets x/26, x/27, 8/30 (firmware)Assistance of all relevant checks (firmware)1-bit framing code error tolerance (switchable)Display:Features selectable via special function register50/60 Hz display (optional 100Hz)Level 1.5 serial attribute display pagesBlanking and contrast reduction output8 direct addressable display pages for SDA 5250-2, SDA 5254-2 to SDA 5257-2
