8.0 PL2303HXD Reference Schematic Diagram

Below is an example of using the PL-2303HX (Chip Rev D) as a USB to RS232 converter (with RS485

option) where a RS232 transceiver (Sipex SP213EHCA) is used to convert the TTL levels serial

interface of the PL2303TA to RS232 levels as well as converting the +5V nominal VCC to the

±9V

required by RS232. The SP213EHCA transceiver provides up to 500Kbps data rate transmission which

is ideal for many designs requiring high speed performance. Contact Prolific FAE for more PCB design

support.
