ASNT8133-KMC

Counter Dividers Overview

The ASNT8133-KMC is a high-speed clock divider fabricated in SiGe technology, offering division ratios of 1, 2, or 4. It accepts fully differential CML input signals with frequencies ranging from DC to 50 GHz. The device provides clean 50% duty cycle outputs via fully differential CML interfaces with 400 mV single-ended swing. Control is managed through CMOS 3.3V logic signals (div and div4). Power consumption is 845 mW at full operational speed, supported by a single +3.3V or -3.3V supply.

Counter Dividers Feature Summary

• Supports selectable output modes including forwarded, divided-by-2, or divided-by-4 based on control signal states.
• Features fully differential CML input and output interfaces with internal termination capabilities.
• Utilizes SiGe fabrication for enhanced performance, yield, and reliability.
• Includes a custom 24-pin CQFP package with a center heat slug for thermal management.

Counter Dividers FAQ

How is the output frequency determined?

The output frequency is controlled by the logic states of the 'div' and 'div4' pins. Logic '0' forwards the input, '1'/'0' divides by 2, and '1'/'1' divides by 4.

What are the power supply options?

The device operates with either a negative supply (Vcc = 0V, Vee = -3.3V) or a positive supply (Vcc = +3.3V, Vee = 0V).
