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.
