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.
