Note:
As applied to
Tables 30, 31,32, 33, 34.
Recommended Operating Conditions are used as test conditions unless
otherwise specified. External voltage reference used with RSET = 360
, VREF = 1.235V, and NTSC CCIR601
operation. Typical values are based on 25
o
C and typical supply levels.
Table 35. CH7003 Supply Current Characteristics
Notes:
5.
The above data is typical at 25
o
C with the following supply voltages: DVDD=3.6
V
, AVDD=5.0V and
VDD=5.0V
6.
Current is mesured in normal circuit configuration with output loads connected; device operating in mode 17
with P-OUT at 2X.
7.
Actual current will depend on many factors, including operating mode, image content, output clock
selections, etc. This table is intended as a general guide only
.
