Texas Instruments TLC6989 LED Display Drivers

Texas Instruments TLC6989 LED Display Drivers provide SPI-Compatible connectivity that controls the TLC698x device family using a standard SPI controller. The device features an internal oscillator to generate the continuous clock required by the TLC698x 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.

The Texas Instruments TLC6989 incorporates fault reporting in the TLC698x daisy chain and TLC6989 internal. It protects the data transmission of register and VSYNC commands to the TLC698x daisy chain and guards the data line for stuck-at faults. A typical application includes SPI-compatible connectivity for TLC6983 and TLC6984 devices.
