Applications Information
How to configure the DS90C2501 with DS90C364 or
DS90CF364A or DS90CF366 for most common applica-
tion:
1. To configure for single pixel in to single pixel out applica-
tion using the DS90C2501 with DS90CF364 or
DS90CF364A or DS90CF366, the “DUAL” pin must be set to
Gnd (single). In this mode, outputs A0-to-A3 and CLK1 are
enabled, and outputs A4-to-A7 and CLK2 are disabled which
reduces power dissipation.
Features Description:
2. Programmable Primary Edge E1: The transmitter is
latching data on both the rising and falling edges of clock
signal coming in on CLKINP pin. The EDGE pin can be used
to program to select the rising edge of CLKINP as the
primary edge E1 or to have the falling edge of CLKINP as the
primary edge E1. However, the logic state of the EDGE pin
must agree with the GUI to generate the correct display.
