The TDA8769 is a BiCMOS 12-bit Analog-to-Digital
Converter (ADC) optimized for GSM/EDGE, W-CDMA and
CDMA2000 radio transceivers, high data rate radios and
other applications such as advanced FM radio and
professional imaging. Its main innovation is the RF
sampling, based on a high-speed clock of up to 105 Msps
combined with high input frequencies of up to 250 MHz.
It converts the analog input signal into 12-bit binary coded
digital words at a maximum sampling rate of 105 MHz.
The TDA8769 analog performances have been proven in
various multi-carrier 3G radio receivers, providing the
best-in-class Adjacent Channel Selectivity (ACS) up to
80 dB.
Moreover the TDA8769 offers the lowest clock cycle
latency, which enables competitive and optimized
feedback loops in controlled systems.
All static digital inputs (TH, CEN, OTC, DEL0 and DEL1)
are CMOS compatible and all outputs are LVTTL and
LVCMOS compatible. A sine wave clock input signal can
also be used.
