The TC2411 is a 14-bit, 1 GSPS digital-to-analog
converter that delivers exceptional high-frequency
performance. The TC2411 is designed to support
single or multiple transmit IF signals up to 500 MHz
and to deliver superior dynamic range at a sampling
rate up to a guaranteed 1 GSPS. A power down
feature has been incorporated into the TC2411
which allows the part to be placed into a Standby
Mode of operation.
•
High resolution
•
High Clock rate
•
Standby Mode for lower power dissipation
Description
As shown in the functional block diagram below, the
TC2411 features a 5-Bit Unary + 9-Bit Binary R2R
architecture. 14-bit straight binary data can be input
to the DAC at a sample rate of up to 1 GSPS. The
DAC
provides
low-noise
and
low-spurious
performance with digital IF input signals across the
first Nyquist band.
The highly linear analog output produced by the
TC2411 may be filtered externally to reject the signal
image, and is suitable for single-stage upconversion
applications.
Applications
The TC2411’s high sample rate makes it ideal for
the following applications:
•
Signal generation
•
Direct digital synthesis (DDS)
•
Test and measurement
•
Software radio
•
Single- and multi-carrier transceivers
•
Radar (Including Burst mode capability)
