iPhone camera circuit repairing

2

00:00:03,366 --> 00:00:07,666

This video mainly explains the meaning of commonly used terms in the camera circuits

3

00:00:09,500 --> 00:00:14,666

Understanding these terms can help us better understand the working principle of the camera circuit,

4

00:00:15,533 --> 00:00:19,100

and also help us quickly find signals in the schematic diagram

5

00:00:22,933 --> 00:00:26,733

In the schematic diagram, the mark CAM means the camera

6

00:00:31,366 --> 00:00:33,633

FCAM represents Front Camera,

7

00:00:35,166 --> 00:00:37,566

RCAM represents Rear Camera

8

00:00:38,666 --> 00:00:44,100

For models above iPhone 7P, the rear camera includes two or three cameras

9

00:00:46,200 --> 00:00:49,900

Different cameras are used to capture objects at different distances,

10

00:00:49,966 --> 00:00:51,600

so they are called differently

11

00:00:52,333 --> 00:00:55,166

WIDE represents wide-angle camera,

12

00:00:55,433 --> 00:00:58,366

SWIDE for the ultra-wide-angle camera,

13

00:00:58,866 --> 00:01:01,300

and TELE for telephoto camera

14

00:01:01,533 --> 00:01:03,466

SHUTDOWN means close or open

15

00:01:05,000 --> 00:01:08,633

Some drawings use SHDN to represent close or open

16

00:01:10,633 --> 00:01:12,433

CLK represents clock,

17

00:01:14,033 --> 00:01:17,033

24M represents 24M clock signal

18

00:01:18,066 --> 00:01:22,100

In iPhone, some cameras will use 24M clock signal

19

00:01:23,566 --> 00:01:26,600

SUPERFLEX represents the ultra-wide-angle camera,

20

00:01:26,733 --> 00:01:29,900

and this logo is generally used on iPhone 12 models

21

00:01:31,966 --> 00:01:34,766

ISP represents Image Signal Processing

22

00:01:36,033 --> 00:01:39,266

LPDP represents Picture Transfer Data Bus

23

00:01:40,633 --> 00:01:44,966

iPhone 7 and above models will use LPDP bus to transmit data

24

00:01:46,433 --> 00:01:48,100

DRIVER represents the drive

25

00:01:49,100 --> 00:01:51,566

SYNC represents the sync signal

26

00:01:51,866 --> 00:01:56,333

STROBE represents strobe, which generally refers to the signal of the flash

27

00:01:57,066 --> 00:01:59,766

Let's understand some terms in the schematic diagram

28

00:02:01,100 --> 00:02:04,366

For example, in the iPhone 8P schematic diagram,

29

00:02:04,466 --> 00:02:11,033

PP1V1_CAM_TELE_DVDD represents the 1.1V power supply of the telephoto camera

30

00:02:11,266 --> 00:02:16,700

AP_TO_TELE_CLK represents the clock signal from the CPU to the telephoto camera

31

00:02:17,633 --> 00:02:20,433

Let's take a look at the iPhone 11 Pro Max model

32

00:02:20,900 --> 00:02:27,500

In the schematic diagram, the mark RCAM_SYNC represents the synchronization signal of the rear camera

33

00:02:27,933 --> 00:02:36,333

CLK_CAM_PMU1_TO_TELE_24M is the 24M clock signal from the camera power supply to the telephoto camera

34

00:02:39,100 --> 00:02:43,533

For another example, in the circuit diagram of iPhone 12 and 12 Pro Max,

35

00:02:43,733 --> 00:02:50,933

the logo PP1V8_WIDE_VDDIO represents the 1.8V power supply of the wide-angle camera

36

00:02:51,133 --> 00:02:58,933

I2C3_CAM_PMU1_SCL_1V8 represents the I2C bus clock from the camera power supply to the camera

37

00:03:00,533 --> 00:03:02,533

That's all for this video
