CLC016 Data Retiming PLL with Automatic Rate Selection

National's Comlinear is a low-cost, monolithic, data retiming phase-locked loop (PLL) designed for high-speed serial clock and data recovery. The CLC016 simplifies highspeed data recovery in multi-rate systems by incorporating auto-rate select (ARS) circuitry on chip. This function allows the user to configure the CLC016 to recognize up to four different data rates and automatically adjust to provide accurate, low-jitter clock and data recovery. A single resistor is used to set each data rate anywhere between 40 Mbps and 400 Mbps. No potentiometers, crystals, or other external ICs are required to set the rate. The CLC016 has output jitter of only 130 pspp a 270 Mbps data rate and 0.25% fractional loop bandwidth. Low phase detector output offset and low VCO injection combine to ensure that the CLC016 does not generate bit errors or large phase transients in response to extreme fluctuations in data transition density. The result is improved performance when handling the pathological patterns inherent in the SMPTE 259M video industry standard. The carrier detect and output mute functions may be used together to automatically latch the outputs when no data is present, preventing random transitions. The external loop filter allows the user to tailor the loop response to the specific application needs. The CLC016 will operate with either or -5.2V power supplies. The serial data inputs and outputs, as well as the recovered clock outputs, allow single- or differential-ECL interfacing. The logic control inputs are TTLcompatible.
