(1) In RMII Mode, the minimum Post Power up Stabilization and Hardware Configuration Latch-in times are 84 ms.

(2) It is important to choose pullup and/or pulldown resistors for each of the hardware configuration pins that provide fast RC time constants in order to latch-in the proper value prior to the pin transitioning to an output driver.

(3) RX_CLK may be held low or high for a longer period of time during transition between reference and recovered clocks. Minimum high and low times will not be violated.

(4) For Normal mode, latency is determined by measuring the time from the first rising edge of TX_CLK occurring after the assertion of TX_EN to the first bit of the “J” code group as output from the PMD Output Pair. 1 bit time = 10 ns in 100 Mb/s mode.

(5) Deassertion is determined by measuring the time from the first rising edge of TX_CLK occurring after the deassertion of TX_EN to the first bit of the “T” code group as output from the PMD Output Pair. 1 bit time = 10 ns in 100 Mb/s mode.

(6) Normal Mismatch is the difference between the maximum and minimum of all rise and fall times.

(7) Rise and fall times taken at 10% and 90% of the +1 or –1 amplitude.

(8) Carrier Sense On Delay is determined by measuring the time from the first bit of the “J” code group to the assertion of Carrier Sense.

(9) 1 bit time = 10 ns in 100 Mb/s mode.

(10) Carrier Sense Off Delay is determined by measuring the time from the first bit of the “T” code group to the deassertion of Carrier Sense.

(11) An attached Mac must drive the transmit signals using the positive edge of TX_CLK. As shown above, the MII signals are sampled on the falling edge of TX_CLK.

(12) RX_CLK may be held low for a longer period of time during transition between reference and recovered clocks. Minimum high and low times will not be violated.

(13) 1 bit time = 100 ns in 10 Mb/s mode.

(14) 10BASE-T RX_DV Latency is measured from first bit of preamble on the wire to the assertion of RX_DV

(15) These specifications represent transmit timings.

(16) Due to the nature of the descrambler function, all 100BASE-TX Loopback modes will cause an initial “dead-time” of up to 550 µs during which time no data will be present at the receive MII outputs. The 100BASE-TX timing specified is based on device delays after the initial 550 µs “dead-time”.

(17) Measurement is made from the first rising edge of TX_CLK after assertion of TX_EN.

(18) Per the RMII Specification, output delays assume a 25-pF load.

(19) CRS_DV is asserted asynchronously in order to minimize latency of control signals through the Phy. CRS_DV may toggle synchronously at the end of the packet to indicate CRS deassertion.

(20) RX_DV is synchronous to X1. While not part of the RMII specification, this signal is provided to simplify recovery of receive data.

(21) CRS ON delay is measured from the first bit of the JK symbol on the PMD Input Pair to initial assertion of CRS_DV.

(22) CRS OFF delay is measured from the first bit of the TR symbol on the PMD Input Pair to initial deassertion of CRS_DV.

(23) Receive Latency is measured from the first bit of the symbol pair on the PMD Input Pair. Typical values are with the Elasticity Buffer set to the default value (01).

(24) X1 to TX_CLK timing is provided to support devices that use X1 instead of TX_CLK as the reference for transmit Mll data.

(25) Latency measurement is made from the X1 Rising edge to the first bit of symbol.

(26) Output delays assume a 25pF load.

(27) CRS is asserted and deasserted asynchronously relative to the reference clock.

(28) CRS ON delay is measured from the first bit of the JK symbol on the PMD Receive Pair to assertion of CRS_DV

(29) CRS_OFF delay is measured from the first bit of the TR symbol on the PMD Receive Pair to deassertion of CRS_DV.

(30) Receive Latency is measured from the first bit of the symbol pair on the PMD Receive Pair. Typical values are with the Elasticity Buffer set to the default value (01).

(31) CLK2MAC characteristics are dependent upon the X1 input characteristics.
