ASNT8143-KMC

Specialized ICS Overview

The ASNT8143-KMC is a SiGe pseudorandom binary sequence (PRBS) generator capable of producing DC to 24 Gb/s output data rates. It supports selectable full-length sequences of 511 bits (polynomial x^9 + x^4 + 1) or 1023 bits (polynomial x^10 + x^7 + 1). The device features fully differential CML input and output interfaces with 400 mV single-ended swing. It includes an additional delayed output for frequency doubling, asynchronous reset functionality, and operates on a single +3.3 V or -3.3 V power supply with 805 mW power consumption.

Specialized ICS Feature Summary

• Generates PRBS-9 (511-bit) or PRBS-10 (1023-bit) sequences via external control signal
• Supports output data rates from DC up to 24 Gb/s
• Provides main and half-period delayed outputs for frequency doubling applications
• Fully differential CML I/O with internal 50 Ohm termination resistors

Specialized ICS Applications

• Testing equipment requiring high-speed pattern generation
• Clock and data recovery (CDR) loop testing
• High-speed serial link characterization

Specialized ICS Procurement Notes

Verify the specific package variant against the datasheet label ASNT8143-KMC, which denotes the custom 24-pin CQFP configuration. Confirm power supply requirements (+3.3V or -3.3V) and ensure PCB layout accommodates the center heat slug soldered to the appropriate ground or power plane as specified in the thermal management section.

Specialized ICS Selection Notes

Select this component when a deterministic pseudo-random pattern source up to 24 Gb/s is required. Ensure the system clock interface supports differential CML signals with the specified voltage levels. Consider the 805 mW power dissipation and the need for adequate thermal management due to the custom CQFP package construction.

Specialized ICS Part Context

Manufactured by Advanced Science And Novel Technology Company, Inc. (ADSANTEC), this IC utilizes SiGe technology. The part number suffix '-KMC' identifies the specific package manufacturer, type, and pinout count within the custom 24-pin CQFP housing. It complies with RoHS standards per EU 2002/95/EC.

Specialized ICS Replacement Considerations

No public confirmed substitute part numbers are available in the documentation. The custom package and specific polynomial configurations may require design adjustments if substituting with other PRBS generators.
