FIN1215MTDX Datasheet, PDF (7/20 Pages) Fairchild Semiconductor – LVDS 21-Bit Serializers / De-Serializers

Transmitter DC Electrical Characteristics
Typical values are at TA=25°C and with VCC=3.3V; minimum and maximum are at over supply voltages and operating
temperatures ranges, unless otherwise specified.

Notes:
7. Positive current values refer to the current flowing into device and negative values means current flowing out of
pins. Voltages are referenced to ground unless otherwise specified (except ΔVOD and VOD).
8. The power supply current for both transmitter and receiver can be different with the number of active I/O
channels.
9. The 16-grayscale test pattern tests device power consumption for a “typical” LCD display pattern. The test
pattern approximates signal switching needed to produce groups of 16 vertical strips across the display.
