74 / 90 page  AD6676 Data Sheet Rev. A | Page 74 of 90 Standby Register Address: 0x150, Reset: 0x02, Name: STANDBY When bits in this register are set, the corresponding blocks enter a power-down state when the chip enters standby mode. Table 63. Bit Descriptions for STANDBY Bits Bit Name Description Reset Access 7 RESERVED 0x0 RW 6 STBY_VSS2GEN 1: power down negative supply (VSS2) generator during standby. 0x0 RW 5 STBY_CLK_PLL 1: power down main clock PLL during standby. 0x0 RW 4 STBY_JESD_PLL 1: power down JESD interface PLL during standby. 0x0 RW 3 STBY_JESD_PHY 1: power down JESD interface transmitters during standby. 0x0 RW 2 STBY_FRAMER 1: power down JESD interface framer logic during standby. 0x0 RW 1 STBY_DATAPATH 1: power down digital datapath during standby. 0x1 RW 0 STBY_DIGCLK 1: disable all digital clocks during standby. 0x0 RW Digital Power-Down Register Address: 0x151, Reset: 0x00, Name: PD_DIG Table 64. Bit Descriptions for PD_DIG Bits Bit Name Description Reset Access [7:3] RESERVED 0x00 RW 2 PD_FRAMER 1: power down JESD interface framer logic. 0x0 RW 1 PD_DATAPATH 1: power down digital datapath. 0x0 RW 0 PD_DIGCLK 1: power down all digital clocks. 0x0 RW Standby Pin Control Register Address: 0x152, Reset: 0x00, Name: PD_PIN_CTRL Table 65. Bit Descriptions for PD_PIN_CTRL Bits Bit Name Settings Description Reset Access [7:5] RESERVED 0x0 RW 4 PD_PIN_EN Enable Standby Mode Control from a GPIO Pin. 0x0 RW 0 Use only register 2 to select standby mode. 1 Use Register 2 or the selected pin to select standby mode. Standby mode is the logical OR of the register setting and the pin state. [3:2] RESERVED 0x0 RW [1:0] PD_PIN_SEL Select GPIO pin for standby control. 0x0 RW 00 Use AGC1 for standby control. 01 Use AGC2 for standby control. 10 Use AGC3 for standby control. 11 Use AGC4 for standby control. Attenuator Mode Register Address: 0x180, Reset: 0x00, Name: ATTEN_MODE Table 66. Bit Descriptions for ATTEN_MODE Bits Bit Name Description Reset Access [7:1] RESERVED 0x00 RW 0 ATTEN_MODE Attenuator Mode. 0x0 RW 0 = Use AGC2 pin to select between values in Register 0x0181 and Register 0x0182. 1 = Use AGC1 and AGC2 pins to decrement/increment attenuation value. |
