Abstract
We demonstrate a novel type of data receiver, which has superior performance compared to a standard receiver when an input signal is distorted by timing jitter. A method and apparatus for improved timing jitter tolerance includes sampling an input signal more than once within a bit slot of the input signal and determining, using logic circuitry, from a combination of at least a subset of the samples, a resulting logic state for an output signal.
Claims21
A method for improving the jitter tolerance of a receiver in an optical transmission system, comprising:
- receiving an input optical signal;
- sampling said input signal more than once within its bit slot;
- and
- determining, using logic circuitry, from a combination of at least a subset of said more than one samples, a resulting logic state for an output signal, wherein said output signal exhibits an improved bit error rate (BER).
