SNLS742A September 2023 – April 2024 DP83TC811-Q1
PRODUCTION DATA
Test mode 1 evaluates transmitter droop. In test mode 1, the DP83TC811-Q1 transmits ‘+1’ symbols for a minimum of 600ns followed by ‘–1’ symbols for a minimum of 600ns. This pattern is repeated continuously until the test mode is disabled.
Test mode 1 is enabled by setting bits[15:13] = 0b001 in the Section 7.6.108.
Additionally, transmit symbol width can be controlled using bits[9:4] in the Section 7.6.55.
