Pin Configuration Table 12. Pin Function Descriptions Pin No. Mnemonic Description 1.0 V Supply H3, H4, H5, H8 to H10, J6, M2, M11 AVDD1.0 1.0 V Clock and Analog Supplies. These pins supply the clock receivers, clock distribution, the on-chip DAC clock multiplier, and the DAC analog core. Clean power supply rail sources are required on these pins. F5 to F8 DVDD1.0 1.0 V Digital Supplies. These pins supply power to the DAC digital circuitry. Clean power supply rail sources are required on these pins. F4, F9 DAVDD1.0 1.0 V Digital to Analog Supplies. These pins can share a supply rail with the DVDD1.0 supply (electrically connected) but must have separate supply plane and decoupling capacitors for the PCB layout to improve isolation for these two pins. Clean power supply rail sources are required on these pins. C1, C2, C5, C7, C8, C11, C12, D6 SVDD1.0 1.0 V SERDES Supplies to the JESD204B Data Interface. Clean power supply rail sources are required on these pins. 1.8 V Supply K3, K5, K7, K10, L3, L6, L7, L10 AVDD1.8 1.8 V Analog Supplies to the On-Chip DAC Clock Multiplier and the DAC Analog Core. Clean power supply rail sources are required on these pins. C6, D3, D10, E3, E10 DVDD1.8 1.8 V Digital Supplies to the JESD204B Data Interface and the Other Input/Output Circuitry, Such as the SPI. Clean power supply rail sources are required on these pins. |
