4Less-TSOC of XLC, QBXOCK, QBTCXO, QBVCXO, SMLDVR and ANLVCO or 4Free-TSOC of XLC, QBXOCK, QBTCXO, QBVCXO, SMLDVR and ANLKVCO

摘要

Even the 4Less-Xtaless, Capless, Indless, Dioless TSOC Design of SOC or 4Free-Xtafree, Capfree, Indfree, Diofree TSOC Design of SOC is developed for the TSOC True System-On-Chip, the 4Less/4Free technologies can still be applied to the conventional XCLK, PMU, etc chip design to have the drastically fantastical improvements over the conventional crystal clock and power management unit chips. The application of 4Less/4Free-TSOC technology to the conventional crystal oscillator to be the QBXOCK Q-Boost Crystal Oscillator Clock, QBTCXO Q-Boost Temperature Cancelling Crystal Oscillator Clock and QBVCXO Q-Boost Voltage Control Crystal Oscillator Clock. Temperature cancelling technique is different from temperature compensation technique. Temperature cancelling technique gets rid of the temperature effect completely. However, the temperature compensation technique still has the residue temperature effect which cannot be compensated with the trimming bits. The application of 4Less/4Free-TSOC technology to the conventional PMU is the SMLDVR Switch Mode & Low Drop Voltage Regulator to have one power supply having two operation modes of switch mode and low drop voltage regulator to have the ultra-extended battery life for portable devices. The application of 4Less/4Free-TSOC technology to the conventional PLL is to have the ANLVCO Adaptive Non-Linear VCO to have the ultra-performance of clock jitter being much less than 1 ps. For the high frequency Network system such as Ethernet, WiMAX, Fiber optics, etc, the ANLVCO is the core technology.
