1.5 TO 2.5 GBPS TRANSCEIVER
SLLS427D − AUGUST 2000 − REVISED JULY 2003
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.
