29 / 60 page ![]() AD9961/AD9963 Rev. 0 | Page 29 of 60 Register Name Register Address Bit(s) Parameter Function 010: 2.0 V. 011: 2.5 V. 100: 3.0 V. 1:0 DAC10B_RNG[1:0] The total range of the DAC extends from top-of-range, to top-of-range minus the span. The span is set as: 00: 2.0 V. 01: 1.5 V. 10: 1.0 V. 11: 0.5 V. DAC10BMSBs 0x46 7:0 DAC10B[9:2] DAC10B voltage control word (eight most significant bits). DAC10BLSBs 0x47 7:2 Unused 1:0 DAC10B[1:0] DAC10Bvoltage control word (two least significant bits). DAC10A Config 0x48 7 DAC10A_EN 0: powers down DAC10A. 1: enables DAC10A. 6:5 Unused 4:2 DAC10A_TOP[2:0] Sets the DAC output voltage at the top range as follows: 000: 1.0 V. 001: 1.5 V. 010: 2.0 V. 011: 2.5 V. 100: 3.0 V. 1:0 DAC10A_RNG[1:0] The total range of the DAC extends from top-of-range to top-of-range minus the span. The span is set as: 00: 2.0 V. 01: 1.5 V. 10: 1.0 V. 11: 0.5 V. DAC10A MSBs 0x49 7:0 DAC10A[9:2] DAC10A voltage control word (eight most significant bits). DAC10A LSBs 0x4A 7:2 Unused 1:0 DAC10A[1:0] DAC10A voltage control word (two least significant bits). TX BIST Control 0x50 7:5 Unused Unused 4 TX_PTTRN Chooses the pattern type for the BIST sequence. 0: selects checker board pattern (0xA5A, 0x5A5, 0xA5A, …). 1: selects PRN output. 3 TX_INSEL 0: selects pattern input from internal pattern generator. 1: selects pattern from the external pins of the Tx port. 2 TX_CONT 0: runs the BIST for 512 cycles. 1: runs the BIST continuously. 1 TX_START 0: keep the BIST engine in an idle state. 1: start the BIST sequence. 0 TX_BISTEN 0: disable the BIST engine. 1: enable the BIST engine. RX BIST Control 0x51 7:5 Unused 4 RX_PTTRN Chooses the pattern type for the BIST sequence. 0: selects checker board pattern (0xA5A, 0x5A5, 0xA5A, …). 1: selects PRN output. 3 RX_INSEL 0: selects pattern input from internal pattern generator. 1: selects pattern from the external pins of the Rx path. 2 RX_CONT 0: runs the BIST for 512 cycles. 1: runs the BIST continuously. |
