9. DVDD: (D-Digital), digital VDD, feem ntau hauv cov digital circuits.
Nco tseg: Yog tias tsis muaj qhov sib txawv ntawm qhov sib txawv-digital ntawm cov circuits lossis cov khoom siv, ces siv VCC thiab VDD.
10. AGND: Analogue GND, sib xws rau qhov tsis zoo ntawm AVCC lossis AVDD.
11. DGND: Digital GND, sib xws rau tus ncej tsis zoo ntawm DVCC lossis DVDD.
12. PGND: (P-Power) hwj chim GND, xws li DC-DC nyob rau hauv lub hwj chim av thiab teeb liab cheeb tsam.
Nco tseg: cov cim saum toj no peb lub zog, qhov tseem ceeb GND, feem ntau yog rau PCB kev sib raug zoo xav tau, muaj qee qhov chaw hauv av lossis ntau qhov chaw ua haujlwm hauv av, txhawm rau kom tsis txhob cuam tshuam, tsuas yog kom paub qhov txawv.
13. VPP: tseem hu ua VPK, voltage ncov-rau-peak, rau sinusoidal signals, uas yog, lub ncov voltage rho tawm lub hav voltage, qhov siab tshaj plaws tus nqi rho tawm yam tsawg kawg nkaus tus nqi.
14. Vrms: (rms-root txhais tau tias squre, nrog lub hauv paus square ntawm lub ntsiab lus), Vrms feem ntau yog hais txog RMS tus nqi ntawm AC teeb liab.
15. VBAT: BAT (BATTERY – luv luv rau roj teeb), feem ntau yog hais txog roj teeb voltage.
16. VSYS: SYS (SYSTEM – system), feem ntau yog hais txog lub platform program (xws li MTK) system fais fab mov.
17. VCORE: (CORE-Core), feem ntau yog hais txog cov tub ntxhais voltage ntawm CPU, GPU thiab lwm yam chips.
18. VREF: REF (reference – reference voltage), xws li cov reference voltage hauv ADC, thiab lwm yam.
19. PVDD: (P-Power), Fais Fab VDD.
20. CVDD: (CORE – core), core power VDD.
21. IOVDD: IO yog GPIO, hais txog GPIO fais fab mov VDD, CAMERA yuav siv rau hauv I2C kev sib txuas lus rub-up fais fab.
22. DOVDD: CAMERA siv sab hauv, los ntawm cov khoom siv sab nraud CAMERA, feem ntau kuj muaj zog analogue.
23. AFVDD: (Auto Focus VDD – Auto Focus VDD power supply), CAMERA yuav siv rau sab hauv, rau lub cev muaj zog fais fab mov.
24. VDDQ: DDR siv hauv DDR, DDR muaj lub teeb liab DQ, tuaj yeem nkag siab tias yog lub zog hluav taws xob rau cov ntaub ntawv teeb liab.
25. VPP: siv nyob rau hauv DDR4, tsis nyob rau hauv DD3, lub npe hu ua lub activation voltage, lo lus me ntsis kab qhib voltage.
26. VTT: feem ntau VTT = 1/2VDDQ, kuj siv rau hauv DDR, muab lub zog rau qee qhov kev tswj cov cim.
27. VCCQ: feem ntau yog siv hauv NAND FLASH, xws li cov xov tooj ntawm tes uas nquag siv EMMC, UFS thiab lwm yam kev nco, feem ntau yog IO fais fab mov.
