3 Description

The TLC69699-Q1 SPI-compatible connectivity

enables TLC696xx-Q1 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-Q1 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-Q1 incorporates reporting of faults in both

the TLC696xx-Q1 daisy chain and TLC69699-Q1

internal. Data transmission of register and brightness

to the TLC696xx-Q1 daisy chain is CRC protected

by TLC69699-Q1. In addition, both the data and

continuous clock lines are guarded by TLC69699-Q1

for stuck-at faults.
