REMARKS：

D D

1. The "NM" is for no mount. (Ex. NM_1K 0402 5%)

2. Document number: 60xxxx It is first six characters of SMT P/N, and change second character to “0”. Ex. If SMT P/N is 6610090001W or 6310090001W, the document number is 601009.

3. Title：SCHEMATIC, x/B Gx-xxx (Function title) It is the description & specification of SMT P/N, and function of each page. Ex. 6310090001W is “SMT M/B T31I GA-010”, and function is “Power Supply”. The title is “SCHEMATIC, M/B GA-010 (Power Supply)”.

4. Rev.：

The schematic revision from AA, after EN modify CML to control AB, AC...... by EDC

From DVT phase, the schematic revision change to BA, after ECO/EN modify CML to control BB, BC... by EDC.

C C

From PVT phase, the schematic revision will change to CA,CB,CC....

5. Size：Units by Millimeters, Size by A3 for standard.

6. Copyright reserved：Each page must have CCI’s copyright reserved.

7. One schematic file for one PCB number

8. Function "Mechanical Parts Template" must include shield-case, and each shield-case must write P/N in this symbol "Part Number" filed.

(1)MT6323 Buck GND(GND_VPROC/GND_VPA/GND_VSYS) is connected together first, and then single trace connect to GND layer

(2)Use single trace >40mil or GND plan to connect buck input bypass cap and MT6323 GND pins of buck in the same layer, and then isolate this GND plan

Backup Batt.

For 32k-less, please change GB301(backup battery) to 22uF cap. Recommend implementing 1~100uF for VRTC, DONOT implement the backup battery. (Because of the Tim e precision: +-1.5 sec every 30 sec)

For longer RTC time sustain after battery remove, please refer to RTC design notice.
