ASNT2011-PQA

Overview

The ASNT2011-PQA is a broadband digital deserializer IC that functions as a 1-to-16 demultiplexer. It accepts serial CML input data at rates from DC to 17 Gbps and outputs 16 parallel LVDS channels operating at fbit/16, up to 1.125 Gbps. The device utilizes a single +3.3V supply with a maximum power consumption of 730 mW. It features internal 50 Ohm termination on high-speed inputs, a divide-by-16 clock path with selectable phase shifts, and operates within an industrial temperature range of -25°C to 125°C junction temperature.

Feature Summary

• Broadband digital deserialization supporting DC to 17 Gbps input rates
• Low-power LVDS output buffers compliant with IEEE Std. 1596.3-1996
• Integrated clock processing block allowing 90-degree phase step selection
• High-sensitivity data input buffer with on-chip 50 Ohm termination

Applications

• High-speed serial link deserialization in telecommunications equipment
• Parallel data distribution for test and measurement instruments
• Broadband signal processing systems requiring low-latency demultiplexing

Procurement Notes

Verify the specific ordering suffix PQA corresponds to the 100-pin QFN package variant when sourcing. Confirm RoHS compliance status per 2011/65/EU standards during acquisition. Ensure thermal management strategies account for the 730 mW power dissipation profile at maximum speeds. Validate that the supplier provides the official datasheet revision 2.4.2 or later for accurate pinout and electrical specifications.

Selection Notes

Select this component when a single-ended or differential CML input must be converted into sixteen parallel LVDS signals. The device is suitable for applications requiring precise clock phase alignment via the CLK Proc block. Consider the 100-pin QFN footprint constraints and the requirement for a stable +3.3V power rail. This part is appropriate for industrial environments given its specified junction temperature range.

Part Context

The ASNT2011 series includes variants such as the ASNT2011-KMA, which shares the same functional architecture but differs in package type. The PQA suffix specifically denotes the 100-pin QFN form factor. This device belongs to ADSANTEC's portfolio of high-speed digital multiplexers and demultiplexers designed for broadband communication infrastructure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the ASNT2011-KMA only if the package difference between QFN and CQFP can be accommodated by the design.

FAQ

How is the phase of the low-speed clock output adjusted?

The phase of the cls output can be modified in 90-degree increments using the phs1 and phs2 CMOS control pins.

What is the maximum data rate supported by the LVDS output buffers?

The LVDS output buffers support data rates up to 1.125 Gbps, corresponding to the fbit/16 division of the 17 Gbps input.

Does the device require external termination resistors for the high-speed inputs?

No, the Data IB and HS CIB buffers utilize on-chip single-ended termination of 50 Ohms to Vcc for each input line.
