1 Because the "official" reference designators used by the original designers of | |
2 the T60N925 board are unknown (no schematics cound be found and there are no | |
3 refdes silkscreen markings), we have to invent our own new refdeses as part of | |
4 the reverse engineering effort. Here are the refdeses I have assigned to the | |
5 major components: | |
6 | |
7 Connectors on the battery/SIM side: | |
8 | |
9 J1 = USB connector | |
10 J2 = headset jack | |
11 J3 = battery connector | |
12 J4 = SIM socket | |
13 J5 = camera connector | |
14 J6 = loudspeaker connects here | |
15 J7 = GSM antenna test connector | |
16 J8 = WLAN antenna test connector | |
17 | |
18 Connectors on the display/keypad side: | |
19 | |
20 J9 = LCD connector | |
21 J10 = keypad board-to-board connector | |
22 J11 = debug FPC connector | |
23 J12 = vibrating motor connects here | |
24 | |
25 MIC1 = microphone | |
26 | |
27 Contact pads on the battery/SIM side: | |
28 | |
29 PAD1 = GSM antenna connection pad | |
30 PAD2 = associated ground pad | |
31 PAD3 = WLAN antenna connection pad | |
32 PAD4 = associated ground pad | |
33 | |
34 Contact pads on the display/keypad side: | |
35 | |
36 PAD5 = earpiece connection pad, left as seen from the front | |
37 PAD6 = earpiece connection pad, right as seen from the front | |
38 | |
39 Pushbutton switches: | |
40 | |
41 SW1 = volume up | |
42 SW2 = volume down | |
43 SW3 = camera button | |
44 | |
45 Major ICs on the battery/SIM side: | |
46 | |
47 U1 = Calypso | |
48 U2 = TWL3014 (Iota) | |
49 U3 = Marvell 88W8385 | |
50 U4 = GSM RF transceiver (TRF6151) | |
51 U5 = GSM RF PA (SKY77328-13) | |
52 U6 = GSM antenna switch | |
53 U7 = Marvell 88W8015 | |
54 | |
55 Major ICs on the display/keypad side: | |
56 | |
57 U8 = S71PL129NC0 flash+RAM | |
58 U9 = SPCA552E | |
59 U10 = LSI ASIC | |
60 U11 = W56940 (ringtone chip) | |
61 U12 = CP2102 | |
62 | |
63 Crystal oscillators: | |
64 | |
65 Y1 = xtal in the GSM RF shieldcan | |
66 Y2 = xtal in the WLAN RF shieldcan |
