Description
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
the V_CC, LVDS V_CC and PLL V_CC of both the transmitter
Pin Diagram
and receiver devices. This change may enable the re-
moval of a 5V supply from the system, and power may
be supplied from an existing 3V power source.
2. The DS90CF383 transmitter input and control inputs ac-
cept 3.3V TTL/CMOS levels. They are not 5V tolerant.
