PROBLEM TO BE SOLVED: To provide a rate negotiation independent of a protocol in use in a PLD receiver-transmitter. SOLUTION: A method for determining a data rate in a serial interface channel for a programmable logic device operating at a clock rate includes; monitoring the channel for occurrence of a single bit transition, and concluding that the data rate is virtually a multiple of the clock rate based on detection of a plurality of single bit transitions in a predefined duration.
