DESCRIPTION

The VSP5610/11/12 are high-speed,

high-performance, 16-bit analog-to-digital-converters

(ADCs) that have four independent sampling circuit

channels for multi-output charge-coupled device (CCD) and complementary metal oxide

semiconductor (CMOS) line sensors. Pixel data from

the sensor are sampled by the sample/hold (SH) or

correlated double sampler (CDS) circuit, and are then

converted to digital data by an ADC. Data output is

selectable in low-voltage differential signaling (LVDS)

or CMOS modes.

The VSP5610/11/12 include a programmable gain to

support the pixel level inflection caused by luminance.

The integrated digital-to-analog-converter (DAC) can

be used to adjust the offset level for the analog input

signal. Furthermore, the timing generator (TG) is

integrated in these devices for the control of sensor

operation.

The VSP5610/11/12 use 1.65 V to 1.95 V for the core

voltage and 3.0 V to 3.6 V for I/Os. The core voltage

is supplied by a built-in low-dropout regulator (LDO).
