The CLM3490 has a 3.3V power supply, 10Mbps, and a slew rate limited RS-485/RS-422 transceiver for RS-485 and RS-422 communication. Each section contains a driver and a receiver. Drivers with slew rate limitations can minimize EMI (electromagnetic interference) and reduce reflections caused by improper cable end connections, allowing for error free data transmission at speeds up to 250kbps. The transmission rate with partial swing rate limitation can reach up to 2.5Mbps, while the transmission rate of CLM3490 can reach up to 10Mbps. Directly replacing international similar products with PIN without changing the circuit board or system software, achieving complete replacement compatibility. Chiplon Microelectronics has developed its own testing plan to ensure that the factory products meet or even exceed the original specifications, supporting industrial grade (0 ℃~70 ℃) working temperatures.
