Clock and timing ICs are components built to provide precise timing and synchronization of electrical signals. The CDCLVP2106RHAR is a clock and timing IC designed specifically for driving high speed higher swing differential signals. Referencing the manufacturer’s datasheet, it can be seen that this device is classified as part of Clock Buffers, Drivers.

The CDCLVP2106RHAR is a high performance, low power CMOS device capable of driving up to 25mA output current into LVDS, CML and LVPECL loads. It has three PLLs and is capable of providing up to four independently selectable output frequencies up to 1000 Mhz. It also offers integrated skew control and jitter cleaning for virtually all differential outputs. A number of modes are available including clock multiplexing, frequency division, and phase seeking.

The device is ideal for applications requiring high speed and low power such as interface and system logic, telecom and optical networks, data storage, PCI Express Gen2, and 3GIO as well as backplane and chip-to-chip signaling. It is also suitable for applications requiring extremely low jitter, such as video transport, switching, and audio and video synchronization.

The working principle of the CDCLVP2106RHAR is based on phase-locked loop (PLL) control. PLLs are used in a variety of applications including frequency synthesis, frequency hopping and clock recovery systems. They use an input reference frequency to generate an output frequency that remains in phase with the input frequency. This is achieved by controlling the phase and frequency of the feedback signal, generated by comparing the input reference and the PLL’s output signal.

The CDCLVP2106RHAR is composed of three independent PLLs. Each PLL provides independently selectable control of up to four output frequencies with up to 4 Mhz frequency step resolution and continuous jitter cleaning. The outputs can be synchronized for low jitter performance. It also provides integrated skew control, eliminating skew problems between signals.

The CDCLVP2106RHAR can be configured to operate in a variety of modes, including normal operation, special “one-shot” modes and non-sequential modes. The device supports spread spectrum clocking, allowing the output frequency to be programmed within the normal frequency range. Additionally, the integrated PLL can be used to delay the input signal by up to 85ns.

In conclusion, the CDCLVP2106RHAR is a highly capable and versatile clock and timing IC designed to provide precise timing and synchronization of differential signals. Its features include up to four independently selectable output frequencies, integrated skew control and jitter cleaning, spread spectrum clocking and input delay support. The combination of these features makes it a suitable solution for a wide range of applications requiring high speed, low power and low jitter performance.
