Hi all,
I'm looking to create a 128 channel ultrasound system using the AFE5809 for the receive system, the LM96530 as the T/R switch, LM96550 as the pulser, and LM96570 to beamform the pulse. An FPGA I was looking through the datasheet for each component, I could not find any information about multi-chip integration -- particularly in the case of the LM96570 as the exact output propagation delay between 2 or more chips is unknown which would preclude any transmit beamforming using the IC. I looked through this question posted previously on the forum: http://e2e.ti.com/support/other_analog/imaging_afes/f/239/t/230591 ,which mentioned the TOD for the beamformer is the same for all channels on the chip, but according to the data sheet, the pulse pattern (so TOD) could be varied for each channel. On the Rx and Tx end, are the propagation delays for each chip known?
I was also thinking of using the SONAR Receiver Path Sub-System Reference Design Using the AFE5809 for the Rx side of the Front end, but noticed the AFE5809 also had an evaluation board. What would be the pro v. con of using this design versus the evaluation board for an imaging system?
Also, I was looking for the schematics for the TX-SDK-V1 or TX-SDK-V2 to design the transmit side of the analog electronics. Are those designs available online or are there corresponding evaluation boards as is the case with the AFE5xx's?
Best,
Jay
