WM8235

210MSPS 9-Channel AFE with Sensor

Timing Generation and LVDS/CMOS Data Output

DESCRIPTION

FEATURES



210MSPS conversion rate

The WM8235 is a 16-bit analogue front end/digitiser IC

which processes and digitises the analogue output signals

from CCD sensors or Contact Image Sensors (CIS) at pixel

sample rates of up to 23MSPS per channel.

16-bit ADC resolution

Current consumption – 390mA

3.3V single supply operation

The device has nine analogue signal processing channels

each of which contains Reset Level Clamping, Correlated

Double Sampling (also Sample and Hold), Programmable

Gain, Automatic Gain Control (AGC) and Offset adjust

functions.

Sample and hold / correlated double sampling

Programmable offset adjust (8-bit resolution)

Flexible clamp timing

Pixel clamp / line clamp mode

Programmable clamp voltage

The output from each of these channels is time multiplexed,

in pairs, into three high-speed 16-bit Analogue to Digital

Converters. The digital data is available in a variety of

output formats via the flexible data port.

Programmable CIS/CCD timing generator

Internally generated voltage references

Compliant for Spread Spectrum Clock

LVDS/CMOS output options

The WM8235 has a user selectable LVDS or CMOS output

architecture.



LVDS 5pair 490MHz 35-bit data

CMOS 90MHz output maximum

An internal 5-bit DAC is supplied for internal reference level

generation. This may be used during CDS to reference CIS

signals or during clamping to clamp CCD signals. An

external reference level may also be supplied. ADC

references are generated internally, ensuring optimum

performance from the device.



Complete on chip clock generator. MCLK 5MHz to 23MHz

Internal timing adjustment

Automatic Gain Control

Automatic Black Level Calibration

56-lead QFN package 7mm x 7mm

Serial control interface

A programmable automatic Black-Level Calibration function

is available to adjust the DC offset of the output data.

The WM8235 features a sensor timing clock generator for

both CCD and CIS sensors. The clock generator can accept

a slow or fast reference clock input and also has a flexible

timing adjustment function for output timing clocks to allow

use of many different sensors.

APPLICATIONS



Digital copiers

USB2.0 compatible scanners

Multi-function peripherals

High-speed CCD/CIS sensor interface
