Part Number: AMC1304M25-Q1 Other Parts Discussed in Thread: ADS1202 , AMC1304M25 Hi team,
Digital filtering is currently being attempted using DFSDM in STM32F7, with filter inputs supporting SPI, Manchester encoding, PDM, and parallel inputs.
Customer has…
Hello Michael,
You actually can feed the modulator output directly into an FPGA. Essentially all that is needed is a digital filter which can be implemented in an FPGA. Most commonly a sinc filter is used, and an example can be found in the ADS1202 reference…
Hi Lakshmi,
From the TMS320F28379D side of things, you would be operating in Mode 0 (refer to Figure 8-56). You would need to caclulate what your divide by ratio needs to be for tc(sdc)m0 to match the MCLK specification for the ADS1202, which is 1MHz…
Hello Y.Ottey,
Yes, it is possible to evaluate a system using the AMC1210EVM with the AMC1303EVM. The clock input of the AMC1210 is compatible with the clock from the AMC1303.
How will this be used in the final system? Where does the filter output go…
Part Number: AMC1305M25 Other Parts Discussed in Thread: ADS1202 Hi,
For customers using AMC1305 and FPGA, do we have Verilog codes for Sinc filter?
Thank you!
Yuan
Hi Zoe!
We have some example VHDL for implementing a Sinc3 filter that you can find under the ADS1202 Reference Design tool folder here:
Scroll down towards the bottom for the VHDL. Many of the FPGA vendors also provide examples oh how to do the Manchester…
Part Number: AMC1203 Other Parts Discussed in Thread: ADS1202 Hi,
I have several questions about the AMC1203. Can you help me to explain them ASAP?
1. Whether the OSR in the AMC1203 document is the same concept as the decimation ratio in the sinc3 filter…
Part Number: AMC1306M05 Other Parts Discussed in Thread: AMC1035 , ADS1203 , ADS1202 Is there a const-sensitive,non-isolated version available?
Just w/o the isolator integrated?
Hi Howard,
Yes, with additional oversampling, you can get higher resolution - but that comes at the cost of speed, more sampling means lower throughput so you have to strike a balance. For non-isolated modulators, there are parts like the ADS1201, ADS1202…
Part Number: TMS320F28379D Other Parts Discussed in Thread: ADS1203 , ADS1202 I have some related questions about the SDFM:
