Notes
1.
All RGB current is sourced from the RGBREF pin. The maximum effective series resistance between RGBREF and
the R, G and B pins is 150
.
Crystal order number 4322 143 05561.
2.
TIMING CHARACTERISTICS
Notes
1.
2.
This parameter is determined by the user software. It must comply with the I
2
C-bus specification.
This value gives the auto-clock pulse length which meets the I
2
C-bus specification for the special crystal frequency.
Alternative, the SCL pulse must be timed by software.
The rise time is determined by the external bus line capacitance and pull-up resistor. It must be less than 1
μ
s.
The maximum capacitance on bus lines SDA and SCL is 400 pF.
