Should I connect to ground the CMLI, CMLQ, FSADJI and FSADJQ pins?

Question Should I connect to ground the CMLI, CMLQ, FSADJI and FSADJQ pins? I'm setting the following AD9716 registers with the following values? Reg Bin Hex 0x04 10000000 80 0x05 00000000 00 0x07 10000000 80 0x08 00000000 00 Answer From your register settings IRseten=1, QRseten=1 and IRcmlen=QRcmlen=0. This means: CMLI and CMLQ should be connected to AVss via a 0ohm resistor. FSADJQ and FSADJI are set as the outputs of the Auxillary DACs. Then you will need to set the AUXDACQ, AUXDACI, AUXCTLQ, and AUXCTLI registers accordingly. More on the Auxillary DACs can be found on page 49 of the datasheet: The latest datasheet can be found at the following ADI link: http://www.analog.com/static/imported-files/data_sheets/AD9714_9715_9716_9717.pd f

AD9716 - Logic Levels at AVDD=3.3V, DVDD=1.8V, DVDDIO=1.8V, CVDD=1.8V

Q I am planning on using the AD9716 with the following power supply voltages: AVDD=3.3V, DVDD=1.8V, DVDDIO=1.8V, CVDD=1.8V Can you please provide the digital specification for this power supply combination? A Here are the required input specifications: For 1.8V supplies DVDDIO = 1.8V and CVDD = 1.8V ViL 0.5v max ViH 1.2v min For both data and the DCLKIO and CLKIN 1.8V Q Channel or DCLKIO Falling Edge Setup time: 0.25ns Hold time: 1.2ns 1.8 V I Channel or DCLKIO Rising Edge Setup time: 0.13ns Hold time: 1.1ns
