JAJSR96A September 2023 – April 2024 DP83TC811-Q1
PRODUCTION DATA
The jabber function prevents the PCS Receive state machine from locking up into a DATA state if the End-of-Stream Delimiters, ESD1 and ESD2, are never detected or received within the rcv_max_timer. When the maximum receive DATA state timer expires, the PCS Receive state machine is reset and transitions into IDLE state. IEEE 802.3bw specifies that jabber timeout be set to 1.08ms ± 54μs. By default, jabber timeout in the DP83TC811-Q1 is set to 1.1ms. This timer is configurable in Section 7.6.54.
