3 Description

The TLC69699 SPI-compatible connectivity enables

TLC696xx device family to be controlled using a

standard SPI controller. The device features an

internal oscillator to generate the continuous clock

required by the TLC696xx device family. Jitter can be

added to the continuous clock for EMI enhancement.

The transmitted data is aligned to the continuous

clock to maintain the timing requirements of the CCSI

interface.

TLC69699 incorporates reporting of faults in both

the TLC696xx daisy chain and TLC69699 internal.

Data transmission of register and brightness to

the TLC696xx daisy chain is CRC protected by

TLC69699. In addition, both the data and continuous

clock lines are guarded by TLC69699 for stuck-at

faults.
