Maximum Sample Rate: 125 MSPS
Test and Measurement Instrumentation
14-Bit Resolution with No Missing Codes
95 dB Crosstalk
DESCRIPTION
Parallel CMOS and DDR LVDS Output Options
ADS62P4X is a dual channel 14-bit A/D converter
3.5 dB Coarse Gain and Programmable Fine
family with maximum sample rates up to 125 MSPS.
Gain up to 6 dB for SNR/SFDR Trade-Off
It
combines
high
performance
and
low
power
consumption in a compact 64 QFN package. Using
Digital Processing Block with:
an internal sample and hold and low jitter clock
– Offset Correction
buffer, the ADC supports high SNR and high SFDR at
– Fine Gain Correction, in Steps of 0.05 dB
high input frequencies. It has coarse and fine gain
options
that
can
be
used
to
improve
SFDR
– Decimation by 2/4/8
performance at lower full-scale input ranges.
– Built-in and Custom Programmable 24-Tap
Low-/High-/Band-Pass Filters
ADS62P4X includes a digital processing block that
consists of several useful and commonly used digital
Supports Sine, LVPECL, LVDS and LVCMOS
functions such as ADC offset correction, fine gain
Clocks and Amplitude Down to 400 mVPP
correction (in steps of 0.05 dB), decimation by 2,4,8
Clock Duty Cycle Stabilizer
and in-built and custom programmable filters. By
Internal Reference; Supports External
default, the digital processing block is bypassed, and
Reference also
its functions are disabled.
64-QFN Package (9mm
× 9mm)
Two output interface options exist
– parallel CMOS
and DDR LVDS (Double Data Rate). ADS62P4X
Pin Compatible 12-Bit Family (ADS62P2X)
includes
internal
references
while
traditional
reference pins and associated decoupling capacitors
APPLICATIONS
have been eliminated. Nevertheless, the device can

also be driven with an external reference. The device
is specified over the industrial temperature range
Software Defined Radio
(
–40°C to 85°C).
