built-in self-test (BIST)

The TLK2501 has a BIST function. By combining PRBS with loopback, an effective self-test of all the circuitry

running at full speed can be realized. The successful completion of the BIST is reported on the

RX_ER/PRBS_PASS terminal.

power-on reset

Upon application of minimum valid power, the TLK2501 generates a power-on reset. During the power-on reset

the RXD, RX_ER, and RX_DV/LOS signal terminals go to a high-impedance state. The RX_CLK is held low.

The length of the power-on reset cycle is dependent upon the REFCLK frequency, but is less than 1 ms.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltage values, except differential I/O bus voltages, are with respect to network ground.
