Overview
The ASNT5131-PQC is a broadband limiting amplifier fabricated in SiGe technology, designed for high-speed signal processing. It supports data rates from DC to 17 Gbps with fully differential CML input and output interfaces featuring internal 50-ohm termination. The device operates on a single +5.0V or -5.0V power supply, consuming 500 mW. It includes an amplitude adjustment tuning port with a 100 MHz bandwidth, allowing adjustable single-ended output amplitude from 0V to 1.0V. Packaged in a standard 24-pin QFN, it exhibits low jitter and stable performance over the industrial temperature range.
Feature Summary
- Provides extremely low jitter broadband signal amplitude control capability using SiGe fabrication technology.
- Features fully differential CML I/Os with integrated 50-ohm termination for flexible AC/DC coupling configurations.
- Includes a dedicated tuning port with 100 MHz bandwidth for precise output amplitude adjustment.
Applications
- High-speed measurement and test equipment
- High-speed proof-of-concept prototyping
Procurement Notes
Verify the specific package suffix 'PQC' corresponds to the 24-pin QFN configuration detailed in the datasheet. Confirm that the ordering information matches the manufacturer's current revision history, as updates may affect pinout drawings or electrical characteristics. Ensure compatibility with the required SiGe process specifications before procurement.
Selection Notes
Select this component when a broadband amplifier supporting up to 17 Gbps is required. It is suitable for designs needing adjustable output amplitude via a dedicated tuning port. Consider the SiGe fabrication for high performance and reliability. Verify power supply requirements (+5V or -5V) and ensure PCB layout accommodates the 24-pin QFN package with appropriate thermal grounding.

FAQ
Can the ASNT5131-PQC operate with both positive and negative power supplies?
Yes, the device can operate with either a negative supply (VEE = -5.0V, VCC = 0V) or a positive supply (VCC = +5.0V, VEE = 0V). Different PCB layouts are required for each configuration.
What is the function of the tp/tn pins?
The tp/tn pins serve as the differential output amplitude control signal inputs. They provide a tuning port with a 100 MHz bandwidth to adjust the output signal amplitude.
