Reference Design
Specifications (measured @ Ta= 25°C, full load after warm up unless otherwise stated)
R-REF03-CAN1
Typical Switching Waveforms
Input and output waveforms of the reference board for a 5Mbit signal
CH1 - TXD
CH2 - CANL
CH3 - RXD
CH4 - CANH
Quick Start Guide
• Apply 3.3V to VCC1/GND1 and observe 5V on the VCC2/GND2. The green LED on the board should light up
• Inject test signal up to 5-Mbit into the TXD input pin (TXD/GND1) using a signal generator or other source
• Check the CANH and CANL signals with a scope on the secondary side (CANH/GND2 and CANL/GND2)
• Check the RXD signal with a scope on the primary side (RXD/GND1)
• Turn off the signal generator
• Turn off the 3.3V supply. The LED should turn off
