8545BGLF

Clock/Timing - Clock Buffers, Drivers are integral components in modern day technology. Among these parts, the 8545BGLF clock buffer driver is a popular choice for many applications. This document will discuss the application field and working principle of the device.

The 8545BGLF is used in applications that require tight match of delay and skew between the outputs. It provides one high frequency input (up to 95MHz) and four outputs that are typically within a just few hundred picoseconds of skew and jitter. Furthermore, the device is able to operate at low power, as it consumes only 1mA of current. This makes it an ideal choice for both mobile applications and embedded systems.

The device is a low-skew, low-jitter clock buffer driver which is bi-directional and ultra high speed. It can handle a frequency range up to 95MHz through its benefits of differential clock input. This is done via the part\'s internal DLL, which is responsible for clock multiplication and improved timing of the user\'s system. It is able to compute jitter performancewith a low input frequency, slow phase-lock-loop, which can sustain phase noise in the low phase noise levels.

At the heart of the device is a fully differential clock generator with internal phase locked loop (PLL). The PLL\'s crystal oscillator serves as the reference clock signal and its output signal is fed back to the input of the oscillator, making the signal ‘lock’ into a predetermined phase signal. As the input signal is adjusted, the device automatically compensates for off-frequency signallock. This ensures that the final output clock is within the exact skew and jitter specifications of the original signal.

It is capable of adjusting and aligning input clock false paths and duty cycles by providing adjustment of the rise/fall times and skew between the fast and slow edges of the signal. This ensures minimal duty cycle distortion as well as provide an improved dynamic response when switching to a 4-phase output.

Finally, the 8545BGLF operates across a wide voltage range from 1.3V to 5.5V and offers on-chip power-down to minimize power consumption. The device can be driven by a single 3V supply or a dual 3V loop, and provides an efficient solution for clock buffers, level shifters for multiple bus topologies, and data multiplexers.

In conclusion, the 8545BGLF clock buffer driver is the designed for applications that require tight match of delay and skew between outputs. It is capable of operating at low power, while ensuring its outputs are within just few hundred picoseconds of skew and jitter. The device includes a fully differential clock generator with its own Phase Locked Loop (PLL) to generate a high-frequency output signal that is in lock with the desired input clock frequency. It supports a wide voltage range, allowing it to be integrated into multiple bus topologies, and offers on-chip power-down mode to minimize power consumption.
