APPLICATIONS

•

Copiers

Facsimile Machines

Scanners

•

16-Bit Resolution

CDS/SH Selectable

Maximum Input Signal Range: 2.0 V

Analog and Digital Hybrid Gain:

DESCRIPTION

–

Analog Gain: 0.5 V/V to 3.5 V/V in

3/64-V/V Steps

Digital Gain: 1 V/V to 2 V/V in

1/256-V/V Steps

The

VSP5620/21/22

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

•

Offset Correction DAC: ±250 mV, 8-Bit

Standard LVDS/CMOS Selectable Output:

–

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.

LVDS:

–

Data Channel: 2-Channel

Clock Channel: 1-Channel

8-Bit/7-Bit Serializer Selectable

The VSP5620/21/22 include a programmable gain to

support the pixel level inflection caused by luminance

and a built-in light-emitting diode (LED) driver to

–

CMOS: 4 Bits × 4

•

Timing Generator

–

Fast Transfer Clock: One Signal

Slow Transfer Clock: One Signal

adjust

the

brightness.

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.

LED Driver: Three Channels

–

Current: 60-mA/Channel Max,

16-Steps/Channel

•

Timing Adjustment Resolution: t_MCLK/48

Input Clamp/Input Reference Level

Internal/External Selectable

The VSP5620/21/22 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).

•

Reference DAC: 0.5 V, 1.1 V, 1.5 V, 2 V

SPI™: Three-Wire Serial

GPIO: Four-Port
