ADSANTEC ASNT8143-KHC

ASNT8143-KHC generates a 511-bit or 1023-bit PRBS using selectable ninth- or tenth-order polynomials. A differential asynchronous active-low reset prevents a locked all-zero sequence state. The device provides a main differential data output and a second sequence output delayed by half a period. The manufacturer specifies clock/data operation from DC to 24 Gb/s under its stated conditions.

The original LCDChip record says 24-CQFN Exposed Pad. Its package registry contains the same normalized name and maps it to /upload/package/24-CQFN-Exposed-Pad.jpg. The ADSANTEC data sheet calls the device a custom 24-pin CQFN with a center heat slug; use its package drawing and pin-number table for the actual footprint. The generic package label alone does not establish mechanical interchangeability.

Layout checks

• Match pin-1 orientation and the ADSANTEC 24-pin drawing.
• Connect the center heat slug as directed for the selected supply configuration.
• Design differential CML traces and terminations for the intended data rate.

The registered JPG is missing locally and returns HTTP 404 on the production site. The manufacturer drawing, not this unavailable generic image, governs the footprint.

The manufacturer's terminal-functions table identifies these exact signals and package pins:

Use the ADSANTEC drawing for orientation. Its electrical table contains a control-signal naming inconsistency; verify OFF10 control levels directly before implementation.

Electrical figures are from ADSANTEC Rev. 1.0.3 under its stated test configuration; absolute-maximum values are not operating targets.

No pin-compatible substitute is established by the manufacturer's document. Compare any proposed generator for exact PRBS polynomials and lengths, differential CML electrical levels, reset behavior, clock/data rate, supply arrangement, 24-pin footprint and thermal-pad connection. The ASNT5150 and ASNT5140 are shown in the manufacturer's external frequency-doubling examples as a MUX and XOR device; they are not replacements for ASNT8143-KHC. No unverified LCDChip alternative link is asserted.

ADSANTEC (Advanced Science And Novel Technology Company) publishes the ASNT8143-KHC Rev. 1.0.3 data sheet with functional description, terminal functions, electrical characteristics and the custom CQFN package drawing. Verify the current controlled revision and exact marking before design or procurement decisions.

Check the ASNT8143-KHC marking, traceability, 24-pin CQFN geometry and heat-slug design against ADSANTEC documentation. Qualify the chosen supply and termination scheme on the actual PCB; a generic package image is insufficient for authenticity or footprint approval.

Review the ADSANTEC terminal table, package drawing, CML termination, reset and supply-configuration instructions for the actual design. Resolve the data-sheet OFF10 naming inconsistency with the manufacturer if precise control thresholds are required. The production package JPG is unavailable; do not publish this draft until the image, footprint and page presentation have been checked.
