3 Description
The 8/4-channel, 16/14-bit ADS52J6x analog-to-
digital converter (ADC) uses CMOS process and
remarkable circuit techniques. The device is designed
to operate at low power and give very high signal-
to-noise ratio (SNR) performance with a 2-Vpp full-
scale input. The ADS52J65 device gives 80dBFS
idle SNR and 78dBFS full scale SNR at 5MHz.
The large input bandwidth of 250MHz makes the
device well suited for a wide range of applications,
such as high frequency medical ultrasound, magnetic
resonance imaging, multi-channel data acquisition,
flow cytometry, and hematology analyzer. The ADC
integrates an internal reference trimmed to match
across devices.

ADS52J6x has advanced digital features, including a
digital I/Q demodulator with fractional decimation filter.
The ADC data from each channel is encoded using
an 8B to 10B format and is sent as a SerDes data
stream using current-mode logic (CML) outputbuffers,
as per the JESD204B standard. The ADC data from
all eight channels can be output over a single CML
buffer (1-lane SerDes) with the data rate limited
to a maximum of 12.8Gbps. Using SerDes outputs
reduces the number of interface lines. This, together
with the low-power design, enables eight channels to
be packaged in a 9mm × 9mm VQFN allowing high
system integration densities. ADS52J6x also supports
modes where all ADC data is sent over four CML
buffers (4-Lane SerDes), reducing the SerDes data
rate per lane for low-cost FPGAs. The ADS52J6x
is available in a non-magnetic VQFN package that
does not create any magnetic artifact. The device is
specified over –40°C to +85°C.
