JAJSES4A February 2018 – April 2020 ADC08DJ3200
PRODUCTION DATA.
The ADC08DJ3200 supports frame and multiframe monitoring for verifying the health of the JESD204B link. If the last octet of a frame matches the last octet of the previous frame, then the last octet in the second frame is replaced with an /F/ (/K28.7/) character. If the second frame is the last frame of a multiframe, then an /A/ (/K28.3/) character is used instead. When scrambling is enabled, if the last octet of a frame is 0xFC then the transmitter replaces the octet with an /F/ (/K28.7/) character. With scrambling, if the last octet of a multiframe is 0x7C then the transmitter replaces the octet with an /A/ (/K28.3/) character. When the receiver detects an /F/ or /A/ character, the receiver checks if the character occurs at the end of a frame or multiframe, and replaces that octet with the appropriate data character. The receiver can report an error if the alignment characters occur in the incorrect place and trigger a link realignment.
