ASNT2017-PQA

Clock Buffers, Drivers Overview

The ASNT2017-PQA is a programmable 1:16 demultiplexer with an integrated full-rate Clock and Data Recovery (CDR) unit. It supports data rates from 12.5 Gb/s to 13.6 Gb/s in CDR mode and up to 17 Gb/s in digital mode. The device converts a serial input into 16 parallel LVDS outputs running at fbit/16. Powered by a single +3.3V supply, it consumes 890 mW at maximum speed. Operating junction temperature ranges from -25°C to 125°C within the 3.14V to 3.47V supply range.

Clock Buffers, Drivers Feature Summary

• Integrated full-rate CDR with Frequency Window Detector for accurate clock and data recovery
• Dual operational modes: CDR mode (12.5-13.6 Gb/s) and broadband digital mode (DC-17 Gb/s)
• Proprietary low-power LVDS output buffers compliant with IEEE Std. 1596.3-1996 and ANSI/TIA/EIA-644-1995
• Supports divided-by-16 or divided-by-64 external reference clocks via the Low-Speed Clock Input Buffer

Clock Buffers, Drivers Applications

• High-speed serial data deserialization
• Clock and data recovery systems
• Parallel data distribution networks

Clock Buffers, Drivers Procurement Notes

Verify the package type matches the 100-pin QFN (12mm x 12mm) specification. Confirm that the application design accommodates the required external passive filter components connected to pins ftr1 and ftr2 for proper CDR operation. Ensure power supply stability within the 3.14V to 3.47V range to maintain specified performance levels.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:16 demultiplexing ratio with integrated CDR is required. Choose CDR mode for bit rates between 12.5 Gb/s and 13.6 Gb/s, or digital mode for frequencies up to 17 Gb/s if an external high-speed clock is available. Verify compatibility with LVDS standards for downstream interfaces and ensure the system can provide the necessary reference clock frequencies (C/16 or C/64).

Clock Buffers, Drivers Part Context

The ASNT2017-PQA belongs to the ASNT2017 series of programmable demultiplexers manufactured by ADSANTEC. It is housed in a standard 100-pin QFN package with an exposed pad for thermal management. The device integrates a tree-type architecture for demultiplexing and includes features such as peak detection and adjustable clock phase selection for precise timing alignment.
