As one of the various integrated circuits from the range of clock/timing chips, the PI49FCT807CTSE is a high-speed, low-skew, rail-to-rail buffer from Pericom Semiconductor Corporation. It is used to drive high-frequencies in conjunction with a low capacitive loading for a variety of applications, such as clock/timing buffering, driving video timing or external signals. This particular model is designed for use with low-voltage logic applications that require full Rail-to-Rail output voltage capability.

The PI49FCT807CTSE is basically a single operator differential receiver chip that features normal and inverted outputs, which are configurable with selectable frequency range. It also provides four 4Ohm to 8Ohm channel drive capability with a high switching frequency of up to 300MHz. This high-speed output along with low power consumption makes the PI49FCT807CTSE ideal for applications in a wide range of industries such as medical, automotive and communication systems.

The PI49FCT807CTSE has an on resistance ratio of 1:2, which is used to increase the input to output transparency while maintaining low-capacitive loading. Its power supply range is 3.0V to 5.5V, while operating at 0 to 70 °C. It also features an over-temperature protection mechanism, to ensure that its maximum operating temperature is not exceeded. Moreover, it has provision for an adjustable output delay of up to 300ns to ensure correct logic level timing.

The working principle of the PI49FCT807CTSE is based on its differential input buffer, which is used to drive the output logic level. This is done by sensing the differential voltage applied to the input and amplifying it accordingly. The device also uses a latch to maintain the output voltage till the next input cycle. The device is then capable of using this information to adjust the on resistance for any given logic transition. This process allows for greater precision and high-speed performance.

Overall the PI49FCT807CTSE from Pericom Semiconductor Corporation is an ideal, high-performance device for a range of different applications that require low-skew and high-frequency operation in a low-power package. Its versatility and performance makes it suitable for a range of industries, while its adjustable output delay ensures correct logic timing even under high-load conditions.
