QUAD 0.6 to 1.5 Gbps TRANSCEIVER
SLLS541 – DECEMBER 2002
detailed description (continued)
built-in self-test (BIST)
The TLK4015 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_PASSx terminal.
power-on reset
Upon application of minimum valid power, the TLK4015 generates a power-on reset. During the power-on reset
the RDx, Rx_ER, and Rx_DV/LOSx signal terminals to go to a high-impedance state. The Rx_CLK is held low.
The length of the power-on reset cycle is dependent upon the GTx_CLK 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.
