2C Timing Requirements
The TVP5146M2 decoder requires delays in the I2C accesses to accommodate the internal processor
timing. In accordance with I2C specifications, the TVP5146M2 decoder holds the I2C clock line (SCL) low
to indicate the wait period to the I2C master. If the I2C master is not designed to check for the I2C clock
line held-low condition, then the maximum delays must always be inserted where required. These delays
are of variable length; maximum delays are indicated in the following diagram:

VBI Data Processor
The TVP5146M2 VDP slices various data services such as teletext (WST, NABTS), closed caption (CC),
wide screen signaling (WSS), program delivery control (PDC), vertical interval time code (VITC), video
program system (VPS), copy generation management system (CGMS) data, and electronic program guide
(EPG or Gemstar) 1x/2x. Table 2-6 shows the supported VBI system.
These services are acquired by programming the VDP to enable the reception of one or more VBI data
standard(s) in the VBI. The VDP can be programmed on a line-per-line basis to enable simultaneous
reception of different VBI formats, one per line. The results are stored in a FIFO and/or registers. Because
of its high data bandwidth, the teletext results are stored in FIFO only. The TVP5146M2 decoder provides
fully decoded V-Chip data to the dedicated registers at subaddresses 800540h to 800543h (see
