PRODUCTION DATA
In the ramp test mode, the JESD204C link layer operates normally, but the transport layer is disabled. Each lane encodes an identical stream of incrementing octet values. The octet value is 0x00 at the beginning of every multiframe (or extended multi-block). The value is increased by 1 for each subsequent octet. If there are more than 256 octets in a multiframe (or extended multi-block), then the value roll back to 0x00 after it reaches 0xFF. In 8b/10b modes, the ramp pattern does not start until the ILAS is completed. In 64b/66b modes, the ramp pattern starts after the serializers are initialized.
