The PI6C185-01QE is a Clock/Timing - Clock Buffers, Drivers, device. It is used when a bidirectional or clock signal needs to be buffered. It takes an input clock signal and reproduces it at a higher drive level with minimal distortion.

The clock buffer provides noise immunity and very low output skew. It features a 1:3 differential fanout, allowing it to generate up to four outputs from its single input. It is designed with output enable drops that improve power dissipation when used in low power applications. This feature allows it to reduce power from the chip-level.

Applications

The PI6C185-01QE Clock/Timing - Clock Buffers, Drivers is suitable for many clock applications. It can be used in Serial ATA (SATA) and Advanced Design System (ADS) Synchronous Serial Interface (SSI) applications, as well as other communications networks. It can also be used in telecom and military systems.

The device is especially well-suited for use in digital switching applications, offering output skew of less than 8ns, and power consumption of 2.2mV on the lower range of load. It can handle data rates up to 250MHz and is available in 32-pin SSOP and QFN packages.

Working Principle

The PI6C185-01QE Clock/Timing - Clock Buffers, Drivers is based on a differential end-to-end architecture. This type of design provides high noise margins, low output skew, high switching speeds, and low power consumption. It also allows for multiple output signals to be generated from a single input.

The device features a differential PECL/LVDS amplifier that is designed to buffer and transmit the input clock signal with minimal distortion. The output frequency of the device can be tuned through a voltage control terminal (VCT) on the chip. The VCT adjusts the frequency of the input signal and adjusts the output frequency accordingly.

The device is also equipped with an output enable (OE) terminal, which is used to enable or disable the output signals. When enabled, the OE terminal enables the amplifier to maintain low power consumption even in the case of heavy data loads. It also ensures lower output skew among different outputs.

Conclusion

The PI6C185-01QE Clock/Timing - Clock Buffers, Drivers is a clock buffer device designed for use in many applications. It is designed to provide high noise margins and low output skew, and supports data rates up to 250MHz. It is available in 32-pin SSOP and QFN packages. The device features a differential PECL/LVDS amplifier and is equipped with an output enable (OE) terminal for improved power consumption.
