Introduction

74FCT3807DPGGI8 is an advanced clock/timing solution for high-speed, high-performance applications. It is used to generate and buffer low jitter and low power clock signals for efficient data transmission and transfer. It is a high-speed, low-jitter clock buffer/driver device for source-synchronous and other high-speed, low-power applications. It is a low-power clock buffer/driver device with a very small pin count (6 pins).

Application Field

The 74FCT3807DPGGI8 is applicable in a wide range of fields. As mentioned, it is a high-speed, low-power clock buffer/driver. It is specifically designed to generate and buffer low-jitter clock signals for source synchronous, serial data communication and the transmission of data over long distances. It is seen in high-speed, low-power applications where the data rate is higher than 400 MHz and the demand for low jitter is particularly high.

The 74FCT3807DPGGI8 is also commonly used in data formatter and time recovery applications like differential/clock recovery, forward/reverse clock compensation, clock multiplication, as well as clock delay and jitter attenuation.

The device can also be used to generate reference clocks for telecom, Ethernet and other generic networking applications. Together with its low jitter performance, these features make the 74FCT3807DPGGI8 an ideal device for clock multiplication, delay and jitter attenuation and clock synthesis.

Working Principle

The 74FCT3807DPGGI8 is a low-power, low-jitter clock buffer/driver device which generates low-jitter clock signals for source synchronous and other applications. It is designed to be designed in to digital clock networks. This device has two major functions. First, it buffers the clock input and provides two identical outputs (OUTA and OUTB) to support high-speed, low-jitter operations. Second, it provides a programmable delay (PD) which is used to adjust timing signals or lower jitter.

The clock input (CLKIN) is connected to the system clock. The device has two separate, buffered outputs (OUTA and OUTB). The OUTA output provides a clock signal, while the OUTB output provides an inverted clock output, which is used to clock data from the source into the system. The programmable delay line (PD) can be used to adjust the timing of the buffered outputs or reduce jitter, depending on the application. Additionally, the device provides eight enable signals (EN) which can be used to enable/disable the buffered outputs.

The working principle behind the 74FCT3807DPGGI8 is simple. When the clock signal is applied to the input, it is buffered and amplified by the device. The buffered signal is then split into two identical signals and sent to the OUTA and OUTB outputs. This allows the device to provide two identical clock signals, eliminating the need for external logic elements. The delay line can be used to adjust the timing of the clock signals or reduce jitter, depending on the application.

The 74FCT3807DPGGI8 also has many advantages compared to other clock buffers. For example, its low power consumption, its low jitter performance, its small pin count and its programmable delay allow the device to be used in a variety of applications. This makes the 74FCT3807DPGGI8 an ideal choice for clock/timing applications.
