Other Parts Discussed in Thread: DAC39RFS10, DAC39RF10, ADC14X250

Tool/software:

Dear TI Team,

We are planning to use DAC and ADC specifications. Below are the key details:

DAC:

Output Power: Adjustable from -10 dBm to 0 dBm.
Reference Clock: 3.5 GHz at 0 to -5 dBm.
Chirp Parameters:
- Bandwidth: ~200 MHz
- Output Frequency Range: 900 MHz to 1600 MHz (Adjustable)
- Sweep Time: ~60 µs
- Ramp Rate: 13 ns (max)

ADC:

Sampling Frequency: Adjustable from 36 MHz to 150 MHz
Clock Stability: ±0.1 ppm
Isolation: Sufficient channel-to-channel isolation is required
Dynamic Range: Minimum 86 dB

Suggestions for suitable DAC and ADC components.

Regards,

Balu

Hi again Balu -

For DAC - I recommend DAC39RFS10 (single Ch) or DAC39RF10 (dual Ch)

For ADC - I recommend ADC14X250 (50-MSPS min clock) or ADC32/34J45

Please note, you can use the product selection tables and filters to quickly find parts that meet your key specs!

Dear Sir,

Thank you for your suggestions regarding the DAC and ADC options. I appreciate your guidance sir.

I would like to add that for our application, we require a Serial or LVDS interface. Could you kindly advise which of the recommended options (or any other) would be best suited for this requirement?

Additionally, if there are any reference designs or evaluation modules available for the selected parts, that would be very helpful for our development process. We are working with a tight schedule and need to deliver our product to the customer within 6 months, so reference materials would greatly support our efforts.

Regards,
Balu
