112 / 116 page  AD9554 Data Sheet Rev. D | Page 112 of 116 Address Bits Bit Name Description 0x1688 [7:3] Reserved Default: 00000b. [2:1] APLL_2 manual cal level APLL_2 reference voltage used during APLL_0 calibration. Set these bits (and issue an IO_UPDATE by writing Register 0x000F = 0x01) before calibrating the APLLs to ensure optimal performance over temperature and voltage extremes. These bits must be set only once per power cycle. Before writing to this register, Register 0x0FFF must be 0xF9. 00b = Reference Voltage 0 (default). 01b = Reference Voltage 1 (recommended). 10b = Reference Voltage 2. 11b = Reference Voltage 3. 0 En APLL_2 man cal level Enables manual control of the VCAL reference setting for APLL_2. 0 = manual control disabled (default). 1 = manual control enabled (recommended). 0x1788 [7:3] Reserved Default: 00000b. [2:1] APLL_3 manual cal level APLL_3 reference voltage used during APLL_0 calibration. Set these bits (and issue an IO_UPDATE by writing Register 0x000F = 0x01) before calibrating the APLLs to ensure optimal performance over temperature and voltage extremes. These bits must be set only once per power cycle. Before writing to this register, Register 0x0FFF must be 0xF9. 00b = Reference Voltage 0 (default). 01b = Reference Voltage 1 (recommended). 10b = Reference Voltage 2. 11b = Reference Voltage 3. 0 En APLL_3 man cal level Enables manual control of the VCAL reference setting for APLL_3. 0 = manual control disabled (default). 1 = manual control enabled (recommended).
