PRODUCTION DATA
The DS90UB635-Q1 features enhanced FPD-Link III diagnostics, system monitoring, and Built-In Self Test capabilities. The device monitors forward channel and back channel data for errors and reports them in the status registers. The device also supports voltage and temperature measurement for system level diagnostics. The Built-In Self Test feature allows testing of the forward channel and back channel data transmissions without external data connections.
The DS90UB635-Q1 can send alarms and sensor status data through the forward channel to monitor the CSI-2 interface, Bidirectional Control Channel (BCC), GPIO voltage sensors and internal temperature sensor. The data can then be accessed through the SENSOR_STS_X registers (0x51) to (0x54) on the compatible linked deserializer. Status bits are always transmitted, and transmission of Alarm bits needs to be enabled from registers (0x1C) to (0x1E) on the serializer.
The CSI-2 error status and alarms on the deserializer SENSOR_STS are: CSI-2 alarm, CSI-2 control error, CSI-2 synchronization error, CSI-2 start of transmission error, CSI-2 checksum error, and CSI-2 ECC 2-bit error. The status for these bits can also be read from registers (0x5D) to (0x60) on the serializer. The BCC error alarm is triggered by are BCC link detect and CRC errors which can be read from register (0x52).
The voltage sense level and voltage sense alarms correspond to Sensor V0 (0x58) and Sensor V1 (0x59). And the temperature sense levels and alarm are monitored from Sensor T (0x5A).
