3 Description

The TLC6989 SPI-compatible connectivity enables

TLC698x device family to be controlled using a

standard SPI controller. The device features an

internal oscillator to generate the continuous clock

required by the TLC698x 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.

TLC6989 incorporates reporting of faults in both the

TLC698x daisy chain and TLC6989 internal. Data

transmission of register and VSYNC commands to the

TLC698x daisy chain is CRC protected by TLC6989.

In addition, the data line is guarded by TLC6989 for

stuck-at faults.
