Output Buffer for up to 12Gb/s

The PMCC_OBUF12G is a differential CML 50Ω terminated output driver for datarates from DC up to 12Gb/s. The buffer can also be used for up to 8GHz clock driving. Depending on input signal level it can work in two modes. If the input signal level is lower than 0.1V p-p, the PMCC_OBUF12G will work as a linear amplifier. When input signal level is higher than 0.1V p-p diff., this macro-block works as a limiting amplifier with 500mV single ended or 1V differential output swing. The buffer features output pattern depended jitter below 0.5ps. For power saving, the buffer has a reduced swing mode (600mV p-p differential). 

Three bit control is provided for biasing current adjustment within ±20% to optimize PMCC_OBUF12G performance for the customer needs.
