ASNT6119A-KMF

Overview

The ASNT6119A-KMF is a high-speed limiting amplifier and driver with integrated 4-tap pre-emphasis. It operates at data rates up to 32.5 Gbps using SiGe technology. The device features adjustable output amplitude, eye cross-point control, and selectable main or additional clock outputs. It utilizes a dual power supply configuration of -4.3V and +3.5V, consuming approximately 4.0W. Control is managed via a high-speed CML 3-wire interface.

Feature Summary

• Integrated four-tap pre-emphasis with user-controlled weights and polarities for signal optimization.
• Built-in clock multiplier allowing operation with doubled internal clock frequency.
• Adjustable single-ended output data eye cross point and amplitude control.
• On-chip linear temperature sensor and duty cycle indicators for monitoring.

Applications

• High-speed serial link driver applications
• Optical communication transmitter modules
• Backplane interconnect systems

Procurement Notes

Verify the specific ordering suffix KMF corresponds to the custom 64-pin CQFP package with center heat slug. Confirm power supply requirements match the specified -4.3V negative and +3.5V floating positive rails. Ensure thermal management solutions accommodate the 4.0W average power consumption during operation.

Selection Notes

Select this component for designs requiring precise pre-emphasis tuning and clock multiplication within a single IC. Consider the CML interface compatibility for both data and clock signals. Evaluate the need for external termination resistors as the device includes on-chip 50 Ohm terminations but requires external matching.

Part Context

This device belongs to ADSANTEC's advanced driver-amplifier family utilizing SiGe fabrication technology. It is designed for broadband digital applications requiring high-speed signal conditioning. The part integrates multiple functions typically found in separate driver and equalizer components.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.

FAQ

How is the pre-emphasis tap weight adjusted?

Tap weights are adjusted using analog control voltages (tune1-4) for linear control or digital signals via the 3-wire interface for discrete activation and inversion.

What is the function of the phadj pin?

The phadj pin activates the clock multiplier and adjusts the delay to achieve a 50% duty cycle for the multiplied clock signal.
