ASNT2016-PQA

Clock Buffers, Drivers Overview

The ASNT2016-PQA is a 1:16 demultiplexer (DMUX) with an integrated full-rate clock and data recovery (CDR) circuit. It supports input data rates from 11.3 Gbps to 12.5 Gbps in CDR mode, or broadband digital operation up to 12.5 Gbps with an external clock. The device accepts RZ and NRZ formats via CML inputs with internal 50 Ohm termination. It outputs 16 parallel LVDS data channels at f_bit/16 (up to 780 Mbps) and two LVDS clock outputs. Powered by a single +3.3V supply, it consumes 730 mW at maximum speed and operates within a junction temperature range of -25°C to 125°C.

Clock Buffers, Drivers Feature Summary

• Integrated full-rate CDR supporting 11.3–12.5 Gbps input data rates
• 1:16 deserialization with low-power LVDS outputs meeting IEEE Std. 1596.3-1996
• Supports both RZ and NRZ input data formats with adjustable thresholding
• Single +3.3V power supply with 730 mW power consumption at 12.5 Gbps

Clock Buffers, Drivers Applications

• High-speed serial link deserialization
• Clock and data recovery for optical or copper interconnects
• Parallel interface generation for ASICs or FPGAs

Clock Buffers, Drivers Procurement Notes

Verify the package type matches the requirement; the datasheet identifies the part as available in a standard 100-pin QFN (12mm x 12mm). Confirm that the application environment stays within the specified -25°C to 125°C junction temperature range. Ensure the design accommodates the required off-chip passive filter components for the CDR loop connected to pins ftr1 and ftr2.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:16 split ratio with integrated clock recovery is needed for data rates between 11.3 and 12.5 Gbps. It is suitable for systems requiring LVDS outputs compliant with IEEE Std. 1596.3-1996. Consider the 730 mW power dissipation and the need for a single +3.3V supply rail. Verify compatibility with RZ or NRZ input signals and ensure the reference clock requirements (C/16 or C/64) align with the system architecture.

Clock Buffers, Drivers Part Context

The ASNT2016-PQA belongs to the ASNT20xx series of high-speed demultiplexers from ADSANTEC. It shares functional similarities with other models in the family but is specifically configured for a 1:16 ratio. The 'PQA' suffix denotes the specific 100-pin QFN package variant. This device is designed for advanced science and novel technology applications requiring robust signal integrity at multi-gigabit speeds.
