ASNT1011-PQA

Overview

The ASNT1011-PQA is a broadband digital serializer and 16-to-1 multiplexer designed for high-speed data transmission. It accepts sixteen parallel LVDS input channels (d00-d15) operating at fbit/16 and serializes them into a single differential CML output stream running at the full bit rate, supporting speeds from DC to 16 Gbps. The device operates on a single +3.3V supply with a maximum power consumption of 660 mW. It features an internal divide-by-16 clock divider that generates a low-speed LVDS clock output (clo/clon) with selectable phase shifts via control pins. The IC is housed in a custom 100-pin QFN package and is characterized for junction temperatures ranging from -25°C to 125°C.

Feature Summary

• Converts sixteen parallel LVDS data inputs into a single high-speed serial CML output stream.
• Includes an internal clock divider-by-16 providing a low-speed LVDS clock output with configurable phase selection.
• Features LVDS-compliant universal input buffers capable of accepting differential or single-ended signals.
• Operates on a single +3.3V power supply with integrated on-chip termination resistors.

Applications

• High-speed point-to-point data transmission over controlled impedance media such as PCB traces or copper coaxial cables.
• Parallel-to-serial conversion in broadband digital communication systems.
• Clock distribution and synchronization circuits requiring phase-adjustable divided clocks.

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and pinout configuration. Ensure the procurement source provides valid RoHS compliance statements per 2011/65/EU. Confirm that the component matches the custom 100-pin QFN physical dimensions specified in the datasheet before integration into the design.

Selection Notes

Select this component when a 16:1 serialization ratio is required with LVDS inputs and CML outputs. Verify that the system clock frequency does not exceed 16 GHz and that the parallel data rate remains within the 1000 Mbps limit per channel. Ensure the application environment supports the specified junction temperature range of -25°C to 125°C and can accommodate the 660 mW power dissipation profile.

Part Context

The ASNT1011 series represents ADSANTEC's broadband digital multiplexer family. The ASNT1011-PQA specifically denotes the variant packaged in a 100-pin QFN format. This model serves as a serializer solution for converting wide parallel buses into high-speed serial links, distinct from lower-channel-count variants like the 4:1 or 8:1 multiplexers in the same product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult ADSANTEC directly for equivalent components or cross-reference options if the ASNT1011-PQA is unavailable.
