    Clock Recovery and Data Retiming IC

    The MC2070 is an integrated clock recovery and data retiming IC intended for high-speed fibre-optic based communications. Using PLL techniques, an on-chip VCO is locked to an incoming NRZ data stream, and both clock and retimed data signals are brought out. Fully differential architecture and low noise design techniques ensure excellent jitter & PSRR performance.

    The PLL features dual control loops for frequency and phase acquisition. The frequency loop acquires the input data frequency, locking onto random or scrambled NRZ data without the need for preamble. At frequency lock (i.e. zero frequency error) this loop has no further effect. The phase control loop then works to ensure that the output phase tracks the input phase. The clock is locked 90 out of phase with the data for maximum jitter immunity.

    Technology: 0.8 BiCMOS
    Package: DIP 16 Pin
