8535-01PGGI Application Field and Working Principle
Clock/Timing - Clock Buffers, Drivers

The 8535-01PGGI is a 1.5V universal clock buffer designed for applications in the fields of computer and consumer electronics. It was developed to optimize system performance, reduce power consumption and to increase the accuracy of clock distribution. This buffer provides the user with a device that is easy to configure and cost effective.

The 8535-01PGGI is a self-timed, often called autonomous, circuit architecture which is capable of operating off of a single clock input. It is designed for applications where multiple clock signals are needed and it can also generate new clock components. The device can be used in a variety of different applications, such as, diverting single clock signals to synchronize the multiplex and cascade clocks of multiple CPUs, or to convert the system clock and local bus timing signals. It can also be used as an oscillator, a delay line, and a frequency divider.

The 8535-01PGGI is a dual port buffer with a configurable clock input on the bottom port, and a design-selectable programmable I/O on the top port. The input can either be a single- or dual-edge clock. The top port is programmable to either a single-end or differential k-out-of-n synchronous output, meaning that up to nine separate copies of the input signal can be provided.

The 8535-01PGGI can be programmed using pins for selecting either a single- or dual-edge clock. The output logic family can also be programmed using a pin for selecting either a single-end or a differential k-out-of-n synchronous output. It is also programmable for adjusting output phase and duty cycle bits.

The operating temperature range of the 8535-01PGGI is -40℃ to 85℃. The absolute maximum junction temperature is 125℃. The device is characterized for operation over a voltage range of 1.5V to 1.95V. It has an adjustable supply voltage that is programmable with a single configuration pin. Additionally, the device has a high sensitivity 17 dB typical common mode threshold for easy passage of large signals.

The 8535-01PGGI is quite an efficient device. It has a wide setup and hold time that enables it to operate down to 1.5 V supply voltage. In addition, the power consumption is very low, so much so that the device can be powered by the same supply that is driving the multiple clock components. The device is also die-stacked with logic blocks, allowing for increased system performance and reduced area.

The 8535-01PGGI has integrated self-test and calibration blocks. This enables the device to perform burn-in testing and provide efficient operation over temperature and voltage variations. In addition, the device includes design isolation to provide excellent isolation between input and output signals which helps to eliminate undesired coupling.

In conclusion, the 8535-01PGGI is a reliable, flexible and cost effective clock buffer. Its low power consumption, high sensitivity, programmable output logic family and integrated self-test and calibration blocks make it ideal for applications requiring high performance at low power. The device can be used for a variety of tasks such as diverting single clock signals to synchronize multiplex and cascade clocks, as well as for frequency dividers, oscillators and delay lines.
