The CA1249 is a full-function clock driver for generating transmit pulses in optical RZ systems operating with clock rates between 10.7 and 12.5 GHz (up to 12.5 Gbps FEC data rates). The CA1249 amplifies clock signals while providing analog phase shift control. Excellent phase shift accuracy, low phase variation over temperature and stable output level performance work in conjunction with the integral power • 10.7 to 12.5 Gbps Clock Rates Tunable 200MHz about any Fo detector to ensure precise control of transmitted pulses. • 360˚Analog Phase Shift Range • 16 Vp-p Output Voltage • Fully Qualified levels with low power consumption.
