A new time-based architecture for serial communication links
Bibliographic record
Abstract
A new time-based architecture for serial communication links is presented in this paper. The design is based on a low-power pulse-position modulator (PPM) as a transmitter and a low-power, single-cycle-latency time-to-digital converter (TDC) as a receiver. Using the proposed architecture, a 4 Gbps link over a 40 inch FR4 channel has been designed using a 1 GHz input clock signal and performance is compared with a serializer/deserializer (SerDes) link with the same data rate. The proposed architecture concentrates the transmitted signal energy in a significantly lower bandwidth than the conventional SerDes system at the same data rate. This allows simpler circuitry at the receiver side to recover the transmitted data, using smaller chip area and lower power dissipation. The technique can be readily expanded to modulate both edges of the signal, and the clock can also be embedded to avoid the need for a separate clock line.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
