Hello jay_col,
Apologies for the delayed response.
The t_h specified in table 3 should be the hold time for rising edge of WRT and the data in (Please refer to figure 2). This does not specify the t_h* shown in figure 64 but rather shows that IQSEL should…
Hi,
Please refer to Rev G of the datasheet.
The minimum Logic 1 value is the minimum input voltage at the logic pin for the device to recognize it as logic 1 or high.
2.1 V is the minimum value. 3 V is the typical value.
Vthreshold is approximate and is not…
Yes, until a clock is applied, the output is indeterminate.
Hi ,
Could you please let me know the –40°C to +85°C as Operating temperature same as Case temperature (Tcase) or is it Ambient Temperature.
Could you please let me know if there is any data with regards ThetaJC .
Thanking you
With best regards and…
About AD9763.
Can you tell me what I should do about unused pins if I use port1 only ?
Unused pins are CLK2/IQRESET,WRT2/IQSEL,DB0-P2~DB9-P2/MSB,IOUTA2 and IOUTB2.
Connecting to ground, power supply, or nothing?
What should I do more except these?
I'm adapting a design from a retired engineer with two discrete AD9705s being used for IQ modulation. I noticed that in an earlier design, he had used a single AD9763. Comparing both of these options, it seems that the two discrete AD9705s beat the AD9763…
