TSW1400EVM: Product selection

FRANK1

Part Number: TSW1400EVM

Hi sir,
Greetings,

Could you please help me selecting a high-speed DAC and pattern-generator evaluation modules

I have a TSW1400; what is the maximum output data rate out of a compatible 2-channel DAC?
I assume I need at least a 10-bit DAC.
I believe it's 9 GS/s at 14-bit, with a TSW14J56EVM and DAC38RF82 combo.
I just want to make sure I can use two channels at 9 GS/s and 14-bit simultaneously, and I would like to know what is the maximum record length.
I need a ~10 GS/s DAC, with as high resolution as possible.
That would be a combination of DAC and pattern generator EVMs.

Thank u.

Regards,
Mark

Mark,

Using the DAC38RF82EVM with the TSW14J56EVM is the fastest solution available today. You would be able to do 2 channels at 9Gs/s with 16 bit input data but would require the DAC to use a minimum of 8x interpolation with complex data. If using real data, the minimum interpolation required would be 4X.

The TSW14J56EVM would be able to support patterns up to 1G samples for each channel.

Regards,

Jim

Mark,

The fastest DAC that can be used with a TSW1400EVM is a 1.5Gs/s DAC34SH84.
