SNLS742A September 2023 – April 2024 DP83TC811-Q1
PRODUCTION DATA
The DP83TC811-Q1 enters silent mode once the sleep_rqst_timer expires or the PHY no longer detects activity on the MDI, indicating that the Link Partner has already moved to silent mode.
Silent mode is only an intermediate state prior to sleep. The PHY sets tx_mode = SEND_Z and (0,0) are transmitted on the MDI. If sleep enable, bit[1] in the Section 7.6.26, is set and no energy is detected on the MDI for the duration of silent_timer (default = 8ms), the DP83TC811-Q1 will enter sleep mode. However, if energy is detected on the MDI prior to silent_timer expiration, the PHY enters standby mode.
