Hi Charles,Thank you again!Q3: So LM96550 CANNOT support CW up to +/-50V. Since the bottleneck is with LM96550, why LM96530 was damaged? I'm sorry that I do NOT really understand what you have said in...

Forum Post: AFE5805 LVDS TEST PATTERNS and LVDS receive
I set EN_RAMP to "1", cause all the channels to output a repeating full-scale ramp pattern, and use altlvds_rx in FPGA to receive the ramp signal, I can see the ramp pattern in Signal Tap,but the data...

Hi Charles,Q3: Yes, their's VSUB pin is connected together. But the four chips LM96550 were NOT demaged yet. And all LM96530 were shorted in this accident.

Haiteng,It looks like your bit [0] and bit [1] get stuck for two cycles. I have never seen this phenomenon in the AFE5805. What is your FPGA solution? Please try some of the other test patterns like...

Hi Charles,Q3: You misunderstood my point. LM96550 was NOT damaged, but LM96530 did. We configured LM96550 to CW mode just by enabling the CW mode bit in the LM96570, while the LM96550 MODE pin was set...

Hi Shiwei,Wow, it's amazing that the LM96550 is not damaged. When power on the LM96530, did you turn on the VSUB first? If yes, it shouldn't have any problem. Which supply/supplies has high...

Hi,Chuck,I use Altera IP altlvds_rx to receive lvds data from AFE5805, deserialization factor is 6, write the rx_out[5..0] into FIFO with rx_outclock(100M), and read from FIFO using 50M clock to splice...

Hi Charles,I am afraid that the demand of VSUB powered on firstly is NOT met strictly. All voltage supplies transform from the input power i.e. +/- 12V and +5V which are supplied simultaneously. So the...
