Bt864A/865A
1.6 Power Saving Modes
YCrCb to NTSC/PAL Digital Video Encoder
1-22
Conexant

1.6 Power Saving Modes
In SLEEP power-down mode (SLEEP pin set to 1), all analog and digital circuitry
is disabled, and total device current consumption approaches 0 mA. Register
states are preserved, but other chip functionality (including I
2
C communication)
is disabled. This mode should be set when the Bt864A/865A may be subjected to
clock and data frequencies outside its functional range.
In DACOFF power-down mode, (DACOFF register is set to 1) all DACs are
disabled and analog current is reduced to approximately 0 mA. All other digital
circuitry remains operational, permitting system timing and other functions to
continue.
When DACs are disabled by either SLEEP or DACOFF, VREF will go to
approximately 0.5 V below VAA.
