IT66121FN
TTL input is 2.5V
PTOTAL
1.2311 / 0.4203
mW
TTL input is 1.8V
Notes:
PTOTAL
1.1199 / 0.4203
mW
1. PTOTAL are calculated by multiplying the supply currents with their corresponding supply voltage and summing up
all the items.
Video Data Bus Mappings
IT66121 supports various input data mappings and formats, including those with embedded control
signals only. Corresponding register setting is mandatory for any chosen input data mappings. Refer
to IT66121 Programming Guide for detailed instruction.

Table 2. Input video format supported by IT66121
Notes:
1. The mapping of this format is the same as Table 5 and the timing diagram is similar to Figure 14 except the syncs
are embedded.
2. The mapping of this format is the same as Table 8 and the timing diagram is similar to Figure 15 except the syncs
are separated.
With certain input formats, not all 24 data input pins are used. In that case, it is recommended to tie the
unused input pins to ground.
