Clock/Timing is an important element in the operation of various systems. It is essential in ensuring that events occur in the right order and at the right moment. To this end, clock buffers, drivers, and other components are often necessary. The 85357AGI-01LF is a part that can be used to control and synchronize signal paths or control registers in high-speed applications. Its application field and working principle can be explored further in this article.

Application Field

The 85357AGI-01LF is a low-jitter, 1.8 V to 6 V level translator and fan-out buffer with clock enable. The device can be used in growing application fields that require high-speed buffering, such as communications and networking. The device helps to reduce voltage differences between signalling domains on the same integrated circuit, providing a reliable communication channel for operating and monitoring system functions.

The device is also used in many serial protocols, including Serial RapidIO, CPRI, Aurora and SMPTE-2022-6. As the protocol requires low jitter, the 85357AGI-01LF can be the perfect fit for the job, providing a perfect fan-out buffer with clock enable.

Working Principle

The 85357AGI-01LF is an integrated circuit that works on the basis of a latch-enable signal. Essentially, the signal is used to determine whether the device will respond to an input or ignore it. When the latch-enable signal is high, the device will respond to the input, while when the latch-enable signal is low the device will ignore the input.

In addition, the device relies on two separate internal clocks, each running at a different frequency. One is used as a reference clock and one as the clock output. The device also has an input clock for receiving a signal from an external source, as well as a differential clock output for phase-alignment.

The device also has an I2C-compliant slave interface which is used for controlling the output from the device. This interface can be used to program the device, configure the clock output and the virtual fan-out, as well as to provide diagnostic capabilities.

Conclusion

The 85357AGI-01LF provides a powerful clock buffer/driver solution that can be used in a variety of applications. Its low-jitter design makes it ideal for high-speed applications, while its programmable I2C slave interface enables quick and easy configuration and diagnostics. With its many features, the device has become a popular choice among engineers looking for reliable, high-speed clock buffering/driving.
