4.8 Power Supply Characteristics

The data was measured using a TLK10xL evaluation board. The current from each of the power supplies is measured and the power dissipation is computed. For the single 3.3-V external supply case the power dissipation across the internal linear regulator is also included. All the power dissipation numbers are measured at the nominal power supply and typical temperature of 25°C. The power needed is given both for the device only, and including the center tap of the transformer for a total system power requirement. The center tap of the transformer is normally connected to the 3.3-V supply, thus the current needed may also be easily calculated.

TLK105L TLK106L t0361-01_lls931.gif
1. Due to the nature of the descrambler function, all 100Base-TX Loopback modes cause an initial dead-time of up to 550 μs during which time no data is present at the receive MII outputs. The 100Base-TX timing specified is based on device delays after the initial 550µs dead-time.
2. Measurement is made from the first rising edge of TX_CLK after assertion of TX_EN.
3. External loopback was measured using very short external cable (approximately 10cm).
4. Since MII loopback introduce extreme short roundtrip delay, some hosts would use PCS Input loopback (Mainly in 100BT).

NOTE

  1. Per the RMII Specification, output delays assume a 25pF load.
  2. 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 de-assertion.
  3. RX_DV is synchronous to XI. While not part of the RMII specification, this signal is provided to simplify recovery of receive data.
  4. “RMII receive clock” mode is not part of the RMII specification that allows synchronization of the MAC-PHY RX interface in RMII mode. Setting register 0x000A bit [0] is required to activate this mode.
