The IDT85304-01PGG8 (hereafter referred to as the IDT85304) is a commonly found clock buffer, driver, and translator used in a variety of computer systems today. It offers various features essential to power efficient systems, making it a popular choice among system architects. This article provides an overview of the features and working principle of the IDT85304, as well as its many applications in clock/timing systems.

The IDT85304 is a single IC clock signal buffering, driver, and translator. It contains seven buffered (non-inverted) outputs capable of driving up to 9-bit point-to-point data paths with low power consumption. The device also includes an on-chip voltage regulator circuit to supply the output buffers, allowing for a wide input voltage range (1.8V to 4.5V). The IDT85304 features very fast rise and fall times of 3.5ns to 4.7ns, making it ideal for high performance systems requiring quick data transfer.

This buffer, driver, and translator works on the principle of translating and buffering the input clock signal, often from a crystal oscillator or other input clock source. The input clock signal is translated from a voltage range of 1.8V to 4.5V to its output voltage range, and then buffered to provide a higher current output than the input signal could provide on its own. The output of the IDT85304 is impedance matched to increase skew tolerance with minimal AC power consumption.

The IDT85304 is used in a variety of applications. It is used as a clock buffer in many systems to provide sync clock signals to multiple components that would not be in sync without buffering. It is used as a driver in many devices to provide a stronger output of the clock signal. It is also used as a translator, as mentioned before, to convert the input clock signal of one voltage range to its output voltage range, allowing it to be sent to different components.

The IDT85304 is also used in variety of clock/timing systems. It is used in SDR and DDR memory systems to provide sync clock signals which enable quick data transfer between the memory and the CPU. It is also used in fiber optic networks to ensure all components receive the same clock/timing signals. It is also used in clock-synchronization and frequency-synthesizer applications.
