PL701-02SC Clock Buffers, Drivers

PL701-02SC is a clock buffer, driver, designed to help propagate precise signals while having good isolation and low signal jitter. It is designed to work in applications such as multi-gigabit serializers and deserializers, high-speed protocol PHY, and clock expansion.

Application Field

The PL701-02SC can be used in the following applications:

• Communication Systems: SerDes and CDR applications, Ethernet, Fibre Channel, SONET/SDH, and OTN.
• High-Speed Protocol PHY: PCI Express and Infiniband.
• Clock Expander: To provide additional fan-out for a single clock.

Working Principle

The PL701-02SC contains two precision buffers, each of which will accept an input HCSL (High-Speed Current Steering Logic) reference clock. The output of each buffer is an LVCMOS , allowing the PL701-02SC to output to a wide variety of logic families. The PL701-02SC also contains a high-impedance input, which is used to cascade multiple devices and thus expand the number of outputs.

To reduce jitter, the PL701-02SC requires a third stage of buffering. This is achieved through the use of a passive delay buffer to provide the necessary de-skew and jitter attenuation. The combination of a precision buffer and the delay buffer reduces the output jitter, compared to a single buffer, and also provides an output signal that has a high degree of isolation from the input signal.

The PL701-02SC is a very low-power device and is optimized for minimal power consumption. This makes it ideal for applications where power efficiency is important.

In summary, the PL701-02SC is a high-performance clock buffer, driver device for clock expansion and distribution, offering very good isolation and low signal jitter. It is suitable for a wide range of applications, from communication systems to high-speed protocol PHY and clock expansion.
