Clock buffers, drivers, and other timing devices are critical for managing signals in digital and analog systems. The 8533AGI-01LF clock buffer from On Semiconductor is designed to reduce signal noise and enhance signal integrity. This article provides an overview of the 8533AGI-01LF application field and working principle.

8533AGI-01LF Application Field

The 8533AGI-01LF is an adjustable, two-channel, dual-mode clock buffer. This clock buffer can be plugged into a standard 0.8 mm, 8-pin TSSOP (Thin Shrink Small Outline Package) package. It is ideal for system clock management in portable systems, such as laptops and notebooks, where power consumption requirements are critical. It is also applicable in communication systems, consumer electronics, industrial and automotive markets.

The 8533AGI-01LF can be used for applications where signal integrity is most important. It can be used for point-to-point signal distribution and signal buffering for long traces and multi-drop configurations. It provides signal isolation between outputs, signal integrity, and EMI/RFI protection.

The 8533AGI-01LF provides two outputs on each of the two channels. It requires an input frequency of 12-124 MHz. Frequency output can be selected between 20-124 MHz and divided by 1, 2, 4, or 8. It also offers an input-receiver-sensitivity feature so that the device is still functional even when the input voltage drops. In addition, it offers selectable duty-cycle-adjustable outputs for between 40%-90% duty cycle and a low-power-shutdown mode.

Working Principle

The 8533AGI-01LF is designed to reduce signal noise and improve signal integrity through its high-performance clock buffering and transmission. The device contains two channels of buffering and transmission: the high-speed and low-speed channels. Each of the two channels contains a multiplexer and two outputs. The multiplexer controls which channel is active and whether the output is high-speed or low-speed.

The high-speed channel is designed to provide high-speed clock buffering, transmission, and steering, while the low-speed channel provides low-speed buffering and transmission. Each of the two channels has a dedicated input, multiplexer, and output. The two outputs are controlled by a two-state logic input. When the logic input is high, the output is high-speed; when the logic input is low, the output is low-speed.

The 8533AGI-01LF also offers sensitivity-adjustment resistance, which is used to increase or decrease the input sensitivity. When the sensitivity is increased, the device is able to maintain its performance even at lower input voltages. This feature is especially useful for applications where the input voltage is not constant and may vary with time.

The 8533AGI-01LF also provides a low-power shutdown mode. When this mode is enabled, the device will reduce its output to a minimum level and will not increase the output unless an active input signal is detected. This feature is useful for applications where power consumption is critical.

In conclusion, the 8533AGI-01LF is an adjustable, two-channel, dual-mode clock buffer with two outputs on each channel. It reduces signal noise and improves signal integrity by providing high-speed clock buffering and transmission and low-power shutdown mode. Furthermore, it has an adjustable sensitivity-adjustment resistance for increased signal-response time and improved performance, even at lower input voltages. With its low power requirement and high performance, the 8533AGI-01LF is ideal for portable systems, consumer electronics, communication systems, and automotive and industrial applications.
