Pin Assignments, 64-Pin TQFP, Per-Channel Functions Ckt Name Type Name/Description ab c d 9 212234 AGND GND Analog Ground. A common AGND, DGND, SGND plane is highly recommended. 8 202335 VDD PWR Analog Power Supply. 7 192436 VFXII Voice Frequency Transmit Input. This node requires a 10 M Ω or 20 MΩ resistance to AGND. The value is dependent upon the gain of the XAG amplifier (register 146). 20 M Ω can be used for any gain setting, 10 M Ω can only be used for XAG gain settings of 0 dB and +6.02 dB. 6 182537 VFROP O Voice Frequency Receive Output, Positive Polarity. This pin can drive 2000 Ω (or greater) loads. 5 172638 VFRON O Voice Frequency Receive Output, Negative Polarity. This pin can drive 2000 Ω (or greater) loads. 4 162839 SLIC0 I/O SLIC Control 0. 3 142940 SLIC1 I/O SLIC Control 1. 64 13 30 51 SLIC2 I/O SLIC Control 2. 63 12 31 52 SLIC3 I/O SLIC Control 3. 62 10 33 53 SLIC4 I/O SLIC Control 4. 60 59 58 57 56 55 54 53 52 61 62 63 64 51 50 49 30 28 27 26 25 24 23 22 21 20 29 VDD SLIC0b 31 32 19 18 17 SLIC1b 13 12 11 10 9 8 7 6 5 4 SLIC0a VDDa FILTV SGND DGND SLIC2b VFROPa 14 15 16 3 2 1 SLIC1a VFXIa AGNDa SLIC4b SLIC3b VFRONa 36 38 39 40 41 42 43 44 45 46 37 SLIC1d VFXId DX0 DGND FS AGNDd VFRONd 35 34 33 47 48 VDD VFROPd BCLK VDDd SLIC4c SLIC0d DX1 TSX0 DR0 |
