ASNT8132-KMC

Counter Dividers Overview

The ASNT8132-KMC is a DC-54GHz broadband clock divider by 2 fabricated in SiGe technology. It features fully differential CML input and output interfaces with internal 50Ohm termination to Vcc. The device operates on a single +3.3V or -3.3V power supply, consuming 630mW. It delivers a high-speed clock output signal qp/qn with a 50% duty cycle from the cp/cn input. The output provides a 400mV single-ended swing and exhibits low jitter of 1 ps peak-to-peak. The component is housed in a custom 24-pin CQFP package.

Counter Dividers Procurement Notes

Verify that the specific ordering suffix matches the required package configuration. Confirm power supply polarity requirements (+3.3V vs -3.3V) as PCB layout differs significantly between configurations. Ensure thermal management provisions are adequate for the 630mW dissipation within the custom CQFP package.

Counter Dividers Selection Notes

Select this component when a broadband divide-by-2 function is required up to 54GHz input frequency. Consider the SiGe fabrication for superior speed compared to standard CMOS. Evaluate the need for differential signaling and the availability of appropriate CML drivers/receivers for system integration.

Counter Dividers FAQ

How does the power supply configuration affect the I/O termination?

When operating with a positive supply (Vcc = +3.3V), all I/Os require AC termination when connected to devices with 50Ohm termination to ground. Different PCB layouts are necessary for each power supply combination.

What is the recommended signaling mode for optimal performance?

The differential DC signaling mode is recommended for optimal performance. In DC-coupling mode, the input signal's common mode voltage must comply with specifications.
