We have designed a board based on CLRC6613 for smartcard operation.
Facing issue with card operation delay and sluggishness in detection (delayed) in some boards.
1. Whats is expected DC voltage between RXN, RXP
2. What is modulation voltage? is it 2.5mV p-p (as per data sheet) but we are getting 0.5Vp-p
3. What is expected voltage VMID (pin 14)
Our observation VMID(Pin 14) getting 1.6V (half of VDD 3.3V). But in some board it goes back to 0.89V.
When Vmid voltage is 1.6V card operation is smooth, with 0.89V card operation is sluggish.
