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
