Hi I'm trying to build a SPI system with ldc 1000.
I got ldc 1000evm and snapped off the ldc1000 & coil part to connect to my fpga board.
Here's my settings for the ldc:
SCLK: 2.5MHz 3.3V clock
LDCLK: 6.25MHa 3.3V clock
VIO: 3.3V
The problem is, even if I set the register values to get the ldc1000 working, nothing happens.
I've waited over 2ms to make the chip power up, and asserted CSB signal and set register address 0x00 to just read the device ID with no success.
I found one thing strange with the chip; SCLK signal and LDCLK signal is fine when disconnected from the chip but if I connect them to LDC1000,
the clock amplitude drops from 3.3V to about 1.7V. Does this phenomenon describe any hints for my failure? Is my LDC1000 dead or something??
Thanks in advance.
