The 8535AG-31LFT is a Clock/Timing - Clock Buffers, Drivers device from IDT. This particular model is an Octal Clock Buffer which can help to easily extend and reduce clock signals, helping to reduce the power consumption of devices and protect EMI/RFI signals for less interference with other circuitry in the same working area. This particular device consists of 8 single-ended, high-frequency non-invertingclock buffers which can be individually enabled and disabled to configure 8 independent outputs, with excellent signal integrity characteristics.

The operating temperature of the 8535AG-31LFT is -40°C to +85°C and it is available in 48-pin TSSOP packages. This particular model has 8 separate output clocks in -31LFT package with output frequencies from 1MHz to 250MHz. This particular model has specific features such as built-in ESDprotection, internal PLL for clock multiplication and frequency mutation, low-power EMI/RFI, and more.

This device has many potential application fields, such as clocking systems with distributed clock networks, automated test equipment, instrumentation, clock distribution, low-power designs and general system synchronization.

The working principle of the 8535AG-31LFT model is relatively simple. When the input clock signal is applied, it goes through the internal PLL and is multiplied or mutated by some predetermined factor, depending on the configuration. This clock signal is then sent to the output buffer stage which amplifies, isolates and drives the output signal with low power EMI and RFI. The output can also be configured to emit multiple clock signals by multiplying and muting the main clock signal.

The specifically designed octal clock buffer of the 8535AG-31LFT model is ideal for low-power designs and features internal pull-up resistors which provide good drive capability. This allows for driving multiple clock signals at the same time, eliminating noise and power consumption when multiple clock signals are required. Additionally, the device features a built-in ESD protection layer to protect the device from ESD pulses.

The device also features an asynchronous reset input which can be used to reset the output clock signals. This feature can be useful if used in distributed clocking systems where the synchronous clock can be stopped, reset and then started up again quickly. By using this asynchronous reset feature, the device can be used efficiently to drive several independent clock networks.

Overall, the 8535AG-31LFT is an excellent example of an octal clock buffer which can be used to reduce power consumption of devices while providing excellent signal integrity characteristics. This device is ideal for distributed clock networks, general system synchronization and low-power designs, providing a great solution for applications which require multiple clock signals.
