12-BIT 30 MSPS DUAL CHANNEL

CCD SIGNAL FRONT END FOR DIGITAL COPIER

FEATURES

APPLICATIONS

Copiers

Dual Channel CCD Signal Processing:

– Correlated Double Sampler (CDS)

– Sample Hold Mode

– Digital Programmable Amplifier

– CCD Offset Correction (OB loop)

Scanners

Facsimiles

DESCRIPTION

The VSP5000 device is a complete application specific

standard product (ASSP) for charge-coupled device

(CCD) line sensor applications such as copiers, scanners,

and facsimiles. The VSP5000 device provides two

independent channels of processing lines and performs

analog front-end processing and analog-to-digital (A/D)

conversion. Each channel has a correlated double

sampler (CDS)/sample hold (SH) circuit, a 14-bit

analog-to-digital converter (ADC), a digital programmable

gain amplifier (DPGA), and an optical black (OB)

correction loop. Data output is 12 bits in length and the

2-channel A/D data is multiplexed and output.

High Performance A/D:

– 12-Bit Resolution

– INL: ±2 LSB

– DNL: ±0.5 LSB

– No Missing Codes

High-Speed Operation

– Sample Rate: 30 MHz (Minimum)

78-dB Signal-To-Noise Ratio (at 0-dB Gain)

Low Power Consumption:

– Low Voltage: 3 V to 3.6 V

– Low Power: 290 mW (Typ) at 3.3 V

– Standby Mode: 20 mW (Typ)

The VSP5000 is available in a 64-lead LQFP package and

operates from a single 3.3-V supply.

Pleasebe aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments

semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date. Products

conform to specifications per the terms of Texas Instruments standard warranty.

Production processing does not necessarily include testing of all parameters.
