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 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 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 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.
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).
