Webthe gapped clock to generate a low-jitter 155.52MHz clock • The mapper creates the client clock rate by deleting pulses from the recovered OTN line rate. Or, the OTN line clock is “gapped” to make the average clock-rate equal the desired client clock-rate • When the OTN carries an asynchronous client (i.e. FC), clock gaps can be added ...

WebFeb 26, 2015 · This quadrature locked loop (QLL) is used to generate accurate clock phases for a 4-channel optical receiver using a forwarded clock at quarter-rate. The QLL drives an ILO at each channel without any repeaters for local quadrature clock generation. Each local ILO has deskew capability for phase alignment.
