  • Frequency control clock tuning circuitry
    Patent number: 8659334
    Abstract: Circuits and a method for tuning an integrated circuit (IC) are disclosed. The IC includes multiple programmable fuses coupled to a control block. The programmable fuses used may be one-time programmable (OTP) fuses. The control block reads settings or data stored in the programmable fuses. A tuning circuit coupled to the control block receives the delay transmitted by the control block. The tuning circuit allows tuning of the IC without changes to the fabrication mask. The tuning circuit may include delay chains to provide additional delay to the IC when needed and the delay in the tuning circuit is configured based on the delay value stored in the programmable fuses and transmitted by the control block.

  • Techniques for performing built-in self-test of receiver channel having a serializer
    Patent number: 8037377
    Abstract: A circuit includes a receiver channel and a built-in self-test circuit. The receiver channel has a serializer and a deserializer. The built-in self-test circuit generates test signals that are transmitted in parallel to the serializer during a test of the receiver channel. The serializer converts the test signals into serial test signals. The deserializer converts the serial test signals into parallel test signals that are transmitted to the built-in self-test circuit.
