must be within 2 MHz

≤ fEXTCLK / N ≤ 24 Mhz

The user can utilize the Register Wizard tool

accompanying DevWare to generate PLL settings

given a supplied input clock and desired output

frequency.

Spread−Spectrum Clocking

To facilitate improved EMI performance, the external

clock input allows for spread spectrum sources, with no

impact on image quality. Limits of the spread spectrum input

clock are:

• 5% maximum clock modulation

• 35 KHz maximum modulation frequency

• Accepts triangle wave modulation, as well as sine or

modified triangle modulations.

Stream/Standby Control

The sensor supports two standby modes: Hard Standby

and Soft Standby. In both modes, external clock can be

optionally disabled to further minimize power consumption.

If this is done, then the “Power−Up Sequence” on page 44

must be followed.

Soft Standby

Soft Standby is a low power state that is controlled

through register R0x301A[2]. Depending on the value of

R0x301A[4], the sensor will go to standby after completion

of the current frame readout (default behavior) or after the

completion of the current row readout. When the sensor

comes back from Soft Standby, previously written register

settings are still maintained.

A specific sequence needs to be followed to enter and exit

from Soft Standby.

To Enter Soft Standby:

1. R0x301A[12] = 1 if serial mode was used

2. Set R0x301A[2] = 0

3. External clock can be turned off to further

minimize power consumption (Optional)

To Exit Soft Standby:

1. Enable external clock if it was turned off

2. R0x301A[2] = 1

3. R0x301A[12] = 0 if serial mode is used
