10 / 65 page AD9142 Data Sheet Rev. 0 | Page 10 of 64 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 2. Pin Configuration Table 9. Pin Function Descriptions Pin No. Mnemonic Description 1 CVDD18 1.8 V PLL Supply. CVDD18 supplies the clock receivers, clock multiplier, and clock distribution. 2 REFP/SYNCP PLL Reference Clock Input, Positive. 3 REFN/SYNCN PLL Reference Clock Input, Negative. 4 CVDD18 1.8 V PLL Supply. CVDD18 supplies the clock receivers, clock multiplier, and clock distribution. 5 RESET Reset, Active Low. CMOS levels with respect to DVDD18. Recommended reset pulse length is 1 μs. 6 TXEN Active High Transmit Path Enable. CMOS levels with respect to DVDD18. A low level on this pin triggers three selectable actions in the DAC. See Register 0x43 in Table 77 for details. 7 DVDD18 1.8 V Digital Supply. Pin 7 supplies power to the digital core, digital data ports, serial port input/output pins, RESET, IRQ1, and IRQ2. 8 FRAMEP Frame Input, Positive. 9 FRAMEN Frame Input, Negative. 10 D15P Data Bit 15 (MSB), Positive. 11 D15N Data Bit 15 (MSB), Negative. 12 DVDD18 1.8 V Digital Supply. Pin 12 supplies the power to the digital core and digital data ports. 13 D14P Data Bit 14, Positive. 14 D14N Data Bit 14, Negative. 15 D13P Data Bit 13, Positive. 16 D13N Data Bit 13, Negative. 17 D12P Data Bit 12, Positive. 18 D12N Data Bit 12, Negative. 19 DVDD18 1.8 V Digital Supply. Pin 19 supplies power to the digital core, digital data ports, serial port input/output pins, RESET, IRQ1, and IRQ2. 20 D11P Data Bit 11, Positive. 21 D11N Data Bit 11, Negative. 22 D10P Data Bit 10, Positive. 23 D10N Data Bit 10, Negative. 24 D9P Data Bit 9, Positive. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 CVDD18 REFP/SYNCP REFN/SYNCN CVDD18 RESET TXEN DVDD18 FRAMEP FRAMEN D15P D15N DVDD18 D14P D14N D13P D13N 17 D12P 18 D12N 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 CS SCLK SDIO IRQ1 IRQ2 DVDD18 DVDD18 D0N D0P D1N D1P DVDD18 D2N D2P D3N D3P D4N D4P AD9142 TOP VIEW (Not to Scale) NOTES 1. EXPOSED PAD (EPAD) MUST BE SOLDERED TO THE GROUND PLANE (AVSS). THE EPAD PROVIDES AN ELECTRICAL, THERMAL, AND MECHANICAL CONNECTION TO THE BOARD. 2. EPAD IS THE GROUND CONNECTION FOR CVSS AND DVSS. |
