Receive data hold from RCLK
RCLK shut off delay from CD assert (Mode 3)
1. Typical values are at 25° C, are for design aid only, are not guaranteed, and are not subject to production testing.
RCLK after CD off
Rcv data through-put delay
CD turn-off delay
Receive block out after TEN off
RCLK switching delay after CD off
1. Typical figures are at 25 °C, are for design aid only, are not guaranteed, and are not subject to production testing.
2. CD Turnoff delay, measured from middle of last bit: timing specification. The value of the last bit does not affect this value.
3. Disables blocking of Carrier Detect during full duplex operation.
TEN setup from TCLK
TXD setup from TCLK
TEN hold after TCLK
TXD hold after TCLK
Transmit start-up delay
Transmit through-put delay
1. Typical values are at 25° C, are for design aid only, are not guaranteed, and are not subject to production testing.
COL (SQE) Delay after TEN off
COL (SQE) Pulse Duration
Power Down recovery time
1. Typical values are at 25° C, are for design aid only, are not guaranteed, and are not subject to production testing.
2. When SQE is enabled (DSQE is Low).
