LVCMOS 1.8V / 3.3V VDDIO Operation
The LVCMOS outputs can operate with 1.8 V or 3.3 V levels
(V

pins: PASS and LOCK.
FPD-LINK OUTPUT
VODSEL
The differential output voltage of the FPD-Link interface is
controlled by the VODSEL input.

SSCG GENERATION — OPTIONAl
The Des provides an internally generated spread spectrum
clock (SSCG) to modulate its outputs. Both clock and data
outputs are modulated. This will aid to lower system EMI.
Output SSCG deviations to ±2.0% (4% total) at up to 35kHz
modulations nominally are available. See
6. This feature may be controlled by pins or by register. The
LFMODE should be set appropriately if the SSCG is being
used. Set LFMODE High if the clock frequency is between 5
MHz and 20 MHz, set LFMODE Low if the clock frequency is
between 20 MHz and 65 MHz.
