1
Polarities for vertical and shutter outputs when the AD9923 is in Standby 3 mode are programmable using the STANDBY3POL register, Address 0xE2 (default register
value = 0x000000).
2
Bit assignments for the STANDBY3POL[23:0] register (Address 0xE2): (MSB) STROBE, MSHUT, VSUB, XSUBCK, VSG8, VSG7, VSG6, VSG3, VSG5, VSG4, VSG2, VSG1, XV13,
XV12, XV11, XV10, XV9, XV8, XV7, XV6, XV5, XV4, XV3, XV2, and XV1 (LSB).
3
Polarities for vertical outputs when the AD9923 is in Standby 1, Standby 2, or if OUTCONTROL = low, are programmable using the STANDBY12POL register,
Address 0xF3 (default register value = 0x3FE000)
4
Bit assignments for the STANDBY12POL[20:0] register (Address 0xF3): (MSB) XSUBCK, VSG8, VSG7, VSG6, VSG3, VSG5, VSG4, VSG2, VSG1, XV13, XV12, XV11, XV10, XV9,
XV8, XV7, XV6, XV5, XV4, XV3, XV2, and XV1 (LSB).
5
VSUB, MSHUT, and STROBE polarities for Standby 1, Standby 2, or if OUTCONTROL = low are controlled by STANDBY3POL.
