Patent ID: 7760796

Claim:
A transceiver for receiving and transmitting data over a network, comprising: a transmitter for receiving a network data signal representative of a signal capable of being transmitted over a network and a control signal for impairing characteristics of the network data signal, and for continuously generating an output signal corresponding to the data signal and the control signal during a predetermined time window; a receiver for continuously receiving the output signal from the transmitter, and for reconstructing the network data signal within the predetermined time window; and a built-in-self-test (BIST) device for generating the network data signal and the control signal, and for providing a clock signal for jitter testing of the network data signal, wherein the BIST device detects erroneous performance by the transceiver based on the reconstructed network data signal, wherein the BIST device includes a jitter control system comprising; a multiplexor for outputting the clock signal; at least one delay timer for delaying an input clock signal: a shift register for controlling the multiplexor; and a controller for controlling the multiplexor and updating the shift register.
