3 Description
The LP5899 SPI-compatible connectivity enables
the LP589x device family to be controlled using
a standard SPI controller. The device features an
internal oscillator to generate the continuous clock
required by the LP589x 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.
LP5899 incorporates reporting of faults in both the
LP589x daisy chain and LP5899 internal. Data
transmission of register and VSYNC commands to
the LP589x daisy chain is CRC protected by LP5899.
In addition, the data line is guarded by LP5899 for
stuck-at faults.
