A 0.18μ CMOS Transceiver Design for High-Speed Backplane Data Communications
Bibliographic record
Abstract
An 8 Gb/s current mode logic (CML) transmitter with multi-tap FIR pre-emphasis has been implemented in 0.18 /spl mu/m CMOS technology and verified to operate with PRBS7 data over a 34 inch FR4 backplane. A half-rate clock retiming circuit for generating symbol-spaced data is proposed to alleviate the speed requirement of the traditional full-rate clock retiming. At the receive side, a frequency and phase-locked clock and data recovery (CDR) circuit incorporates a multiphase voltage-controlled oscillator (VCO) and a half-rate bang-bang phase/frequency detector (PFD) with embedded data retiming. The total power dissipation of the transceiver is 75 mW at a 1.8 V supply.

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.
