TDA8768A

12-bit, 70 Msps Analog-to-Digital Converter (ADC)

Rev. 02 — 03 July 2002

Product data

1. Description

The TDA8768AH is a biCMOS 12-bit Analog-to-Digital Converter (ADC) optimized for

GSM and EDGE cellular infrastructures, professional telecommunications and

imaging, and advanced FM radio. It converts the analog input signal into 12-bit binary

coded digital words at a maximum sampling rate of 70 MHz. All static digital inputs

(SH, CE and OTC) are TTL and CMOS compatible and all outputs are CMOS

compatible. A sine wave clock input signal can also be used.

2. Features

■ 12-bit resolution

■ Sampling rate up to 70 MHz

■ −3 dB bandwidth of 245 MHz

■ 5 V power supplies and 3.3 V output power supply

■ Binary or twos complement CMOS outputs

■ In-range CMOS compatible output

■ TTL and CMOS compatible static digital inputs

■ TTL and CMOS compatible digital outputs

■ Differential AC or PECL clock input; TTL compatible

■ Power dissipation 550 mW (typical)

■ Low analog input capacitance (typical 2 pF), no buffer ampliﬁer required

■ Integrated sample-and-hold ampliﬁer

■ Differential analog input

■ External amplitude range control

■ Voltage controlled regulator included

■ −40 °C to +85 °C ambient temperature.

3. Applications

■ High-speed analog-to-digital conversion for:

◆ Cellular infrastructure (GSM and EDGE)

◆ Professional telecommunication

◆ Advanced FM radio

◆ Radar

◆ Imaging (camera scanner)

◆ Set Top Box (STB)

◆ Medical imaging.
