ClampOut and Moire Signal
Clamp Output signal
The clamping pulse generator can control the
pulse width and polarity signal and can be
configured as pseudo-front porch or back porch.
To use the ClampOut signal:
– Select the Clamping Pulse width:
BP0/BP1 bits in MCR register
– Program the Clamp polarity:
CLPINV bit in POLR register
– Select the ClampOut signal as back-porch (after
falling edge of HSYNCO) or pseudo-front porch
(after the rising edge of HSYNCO):
HS0/HS1 bits in MCR register.
– Enable the CLAMPOUT signal:
CLMPEN bit in ENR register
Moire Signal
The Moire output signal is available (instead of the
clamping signal) to reduce the screen Moire effect
and improve color transitions.
The CLAMPOUT pin is alternatively used to output
a Moire signal.
The output signal toggles at each HFBACK rising
edge. After each VFBACK falling edge, the value
of the Moire output is the opposite of the previous
one, independent of the number of HFBACK
pulses during the VFBACK low level.
To use the Moire signal:
– Select the Moire signal:
Reset the BP0/BP1 bits in MCR register
– Enable the output signal:
CLMPEN bit in ENR register

Maximum delay:
Programmable clamping width: 0, 167ns, 333ns, 666ns
-
(Fixed delay of 10 to 30ns) + (fOSC/2) = approx. 110ns.
