2C Timing Requirements
The TVP5154A decoder requires delays in the I2C accesses to accommodate its internal processor's
timing. In accordance with I2C specifications, the TVP5154A 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, the maximum delays must always be inserted where required. These delays are of
variable length; maximum delays are indicated in the following diagram:

If the SCL pin is not monitored by the master to enable pausing, a delay of 128 s should be inserted between transactions for registers
00h through 8Fh.
