Non−Zero and Zero Row Overhead Time (ROT) Modes

In pipelined global shutter mode, the integration and

readout are done in parallel. Images are continuously read

out and integration of frame N is ongoing during readout of

the previous frame N−1. The readout of every frame starts

with a Frame Overhead Time (FOT), during which the

analog value of the pixel diode is transferred to the pixel

memory element. After the FOT, the sensor is read out line

by line and the readout of each line is preceded by a Row

Overhead Time (ROT) as shown in Figure 14.

In Reduced/Zero ROT operation mode (refer to

Figure 15), the row blanking and kernel readout occur in

parallel. This mode is called reduced ROT as a part of the

ROT is done while the image row is readout. The actual ROT

can thus be longer, however the perceived ROT will be

shorter (‘overhead’ spent per line is reduced).

This operation mode can be used for two reasons:

• Reduced total line time.

• Lower power due to reduced clock−rate.

Sensor States

Low Power Standby

In low power standby state, all power supplies are on, but

internally every block is disabled. No internal clock is

running (PLL / LVDS clock receiver is disabled).

All register settings are set to their default values (see

Table 35).

Only a subset of the SPI registers is active for read/write

in order to be able to configure clock settings and leave the

low power standby state. The only SPI registers that should

be touched are the ones required for the ‘Enable Clock

Management’ action described in Enable Clock

Management − Part 1 on page 16

Standby (1)

In standby state, the PLL/LVDS clock receiver is running,

but the derived logic clock signal is not enabled.

Standby (2)

In standby state, the derived logic clock signal is running.

All SPI registers are active, meaning that all SPI registers

can be accessed for read or write operations. All other blocks

are disabled.

Idle

In the idle state, all internal blocks are enabled, except the

sequencer block. The sensor is ready to start grabbing

images as soon as the sequencer block is enabled.

Running

In running state, the sensor is enabled and grabbing

images. The sensor can be operated in global master/slave

modes.

User Actions: Power Up Functional Mode Sequences

Power Up Sequence

Figure 17 shows the power up sequence of the sensor. The

figure indicates that the first supply to ramp−up is the

vdd_18 supply, followed by vdd_33 and vdd_pix

respectively. It is important to comply with the described

sequence. Any other supply ramping sequence may lead to

high current peaks and, as consequence, a failure of the

sensor power up.

The clock input should start running when all supplies are

stabilized. When the clock frequency is stable, the reset_n

signal can be de−asserted. After a wait period of 10 ms, the

power up sequence is finished and the first SPI upload can

be initiated.

NOTE: The ‘clock input’ can be the CMOS PLL clock

input (clk_pll), or the LVDS clock input

(lvds_clock_inn/p) in case the PLL is bypassed.

Enable Clock Management − Part 1

The ‘Enable Clock Management’ action configures the

clock management blocks and activates the clock generation

and distribution circuits in a pre−defined way. First, a set of

clock settings must be uploaded through the SPI register.

These settings are dependent on the desired operation mode

of the sensor.

Table 6 shows the SPI uploads to be executed to configure

the sensor for P1−SN/SE 8−bit and 10−bit serial, with and

without the PLL.

If the PLL is not used, the LVDS clock input must be

running.

It is important to follow the upload sequence listed in

Table 6.

Use of Phase Locked Loop

If PLL is used, the PLL is started after the upload of the

SPI registers. The PLL requires (dependent on the settings)

some time to generate a stable output clock. A lock detect

circuit detects if the clock is stable. When complete, this is

flagged in a status register.

Check the PLL_lock flag 24[0] by reading the SPI

Management− Part 2’ action can be continued. When PLL

is not used, this step can be bypassed as shown in Figure 16

on page 14.
