Product specification
10-bit converter interface (ADC/DAC) for
quadrature transceiver
TDA8779H
FEATURES
Two 10-bit ADCs with multiplexed outputs
Two 10-bit DACs with multiplexed inputs
Sampling rate for the ADCs and DACs up to 20 MHz
Digital outputs (for the ADC) and inputs (for the DAC)
are TTL/CMOS compatible
Internal reference voltage regulator
Power dissipation 520 mW
Standby mode.
APPLICATIONS
Wireless communication.
GENERAL DESCRIPTION
The TDA8779 contains two 10-bit high speed ADCs and
two 10-bit DACs for wireless communication (for use in
transceiver modules). This device converts two analog
input signals (channels I and Q) and digital inputs
(D0 to D9) at a maximum sampling rate of 20 MHz.
The input bias voltages for the analog input voltages are
provided internally at the middle code. The analog input
and output voltages are AC coupled.
The data sampling is performed on the rising edge of the
clock for ADCs and DACs.
All reference voltages are generated internally.
