| 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 |
