DS90CF383 Pin Description — FPD Link Transmitter
Applications Information
The DS90CF383 and DS90CF384 are backward compatible
with the existing 5V FPD Link transmitter/receiver pair
(DS90CF583 and DS90CF584). To upgrade from a 5V to a
3.3V system the following must be addressed:
1. Change 5V power supply to 3.3V. Provide this supply to
