10-to-112-Gb/s DSP-DAC-Based Transmitter in 7-nm FinFET With Flex Clocking Architecture
Bibliographic record
Abstract
This article presents a multiprotocol DSP-DACbased SerDes architecture. The lookup table (LUT)-based DSP provides flexible number of taps for equalization, and soft switching driver allows 1.2-Vpp transmit swing to achieve higher SNR. The architecture employs cascaded phase-locked loop (PLL)based flexible clocking to support a wide range of data rates from 10 to 112 Gb/s. The LC PLL generates 10.25-14.5 GHz but distributes a divided version of the clock between 2.25 and 3.625 GHz with less than 140-fs integrated jitter. The local ring PLL multiplies the clock to 28 GHz but keeps the jitter less than 180 fs thanks to wide loop bandwidth. The transmitter is implemented in 7-nm FinFET consuming 175 mW with 1.56-pJ/bit efficiency.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
