Forum Post: RE: Interfacing AFE5804 with TSW 1405
Hi Chuck, The issue still remains unsolved. Does the adapter connect AFE5804 to (any) FPGA? or to TSW1405? Is it possible to connect TSW1405 and AFE5804 ? I was not able to find a connector connecting...

Hi, Looking at using LM96551 in an industrial ultrasound application. We want to use it with low frequency ultrasound (40Khz - 100Khz). The datasheet for LM96551 says minimum frequency is 1Mhz, but...

Hello Stomp, The lower operating frequency (40kHz - 100kHz) is not an issue with the LM96551 . Regards, Hooman

Hello again Stomp, Just be careful with exceeding the device power dissipation which may possibly happen easier at this lower operating frequency if you don't keep close tabs on the safe waveform duty...

Sam, Your configuration is correct for the CW Voltage Output mode (Figure 103). Also, see the Design database for the AFE5809 EVM here: https://txn.box.com/s/7exnwc5h9jf12cr49ojc2evpegzu5nda Do you...

Sam, About the routing constraints: Obviously each diff pair needs to be matched length. But also, all channels need to be matched length up to the common point. With CW doppler the phase is very...

Hi Chuck Thanks a lot. Yes i want the GERBER file (i can read it without difficulty). For the Design database ( AFE5809 EVM), can you say me what software can i use to read it. Best regards Sam
View ArticleForum Post: RE: AFE5801- DCLK 60 MHz or 120 MHz?
Hello Chuck: Thanks for the clarification. Assuming FCLK (frame clock) = 10 MHz, rate at which the inner or deserialize While Loop should execute is 60 MHz. FYI- We need to build DDR logic block +...
