9mm QFN Package
The LTC
®
2220 and LTC2221 are 170Msps/135Msps, sam-
pling 12-bit A/D converters designed for digitizing high
frequency, wide dynamic range signals. The LTC2220/
LTC2221 are perfect for demanding communications
applications with AC performance that includes 67.5dB
SNR and 80dB spurious free dynamic range for signals
up to 170MHz. Ultralow jitter of 0.15ps
RMS
allows
undersampling of IF frequencies with excellent noise
performance.
DC specs include
±0.4LSB
INL (typ),
±0.3LSB
DNL (typ)
and no missing codes over temperature. The transition
noise is a low 0.5LSB
RMS
.
The digital outputs can be either differential LVDS, or
single-ended CMOS. There are three format options for
the CMOS outputs: a single bus running at the full data rate
or two demultiplexed buses running at half data rate with
either interleaved or simultaneous update. A separate
output power supply allows the CMOS output swing to
range from 0.5V to 3.6V.
The ENC
+
and ENC
inputs may be driven differentially or
single ended with a sine wave, PECL, LVDS, TTL, or CMOS
inputs. An optional clock duty cycle stabilizer allows high
performance at full speed for a wide range of clock duty
cycles.

Why is analog signal processing still recommended when digital signal processing systems are so inexpensive and powerful?
A: Because sometimes analog signal processing is even cheaper and can do things that digital signal processing cannot. The sales of analog signal processing circuits prove this statement. The Science ...
