The LTC
1743 is a 50Msps, sampling 12-bit A/D con-
verter designed for digitizing high frequency, wide
dynamic range signals. Pin selectable input ranges of
±
1V
and
±
1.6V along with a resistor programmable mode
allow the LTC1743’s input range to be optimized for a
wide variety of applications.
The LTC1743 is perfect for demanding communications
applications with AC performance that includes 72.5dB
SNR and 85dB spurious free dynamic range. Ultralow jitter
of 0.3ps
RMS
allows undersampling of IF frequencies with
excellent noise performance. DC specs include
±
1LSB
maximum INL and
±
0.8LSB DNL over temperature.
The digital interface is compatible with 5V, 3V and 2V logic
systems. The ENC and ENC inputs may be driven differen-
tially from PECL, GTL and other low swing logic families or
from single-ended TTL or CMOS. The low noise, high gain
ENC and ENC inputs may also be driven by a sinusoidal
signal without degrading performance. A separate output
power supply can be operated from 0.5V to 5V, making it
easy to connect directly to any low voltage DSPs or FIFOs.
The 48-pin TSSOP package with a flow-through pinout
simplifies the board layout.
