ADC12DJ4000RF 8-GSPS Single-Channel or 4-GSPS Dual-Channel, 12-bit, RF-

Sampling Analog-to-Digital Converter (ADC)

1 Features

3 Description

•

ADC core:

The ADC12DJ4000RF device is an RF-sampling,

giga-sample, analog-to-digital converter (ADC) that

can directly sample input frequencies from DC to

above 10 GHz. ADC12DJ4000RF can be configured

as a dual-channel, 4 GSPS ADC or single-channel,

8 GSPS ADC. Support of a useable input frequency

range of up to 10 GHz enables direct RF sampling

of L-band, S-band, C-band, and X-band for frequency

agile systems.

– 12-bit resolution

– Up to 8 GSPS in single-channel mode

– Up to 4 GSPS in dual-channel mode

Performance specifications:

– Noise floor (–20 dBFS, V_FS= 1 V_PP-DIFF):

•

Dual-channel mode: –152.3 dBFS/Hz

Single-channel mode: –155.0 dBFS/Hz

– ENOB (dual channel, F_IN= 2.4 GHz): 8.8 Bits

Buffered analog inputs with V_CMIof 0 V:

– Analog input bandwidth (–3 dB): 8 GHz

– Usable input frequency range: > 10 GHz

– Full-scale input voltage (V_FS, default): 0.8 V_PP

Noiseless aperture delay (t_AD) adjustment:

– Precise sampling control: 19-fs Step

– Simplifies synchronization and interleaving

– Temperature and voltage invariant delays

Easy-to-use synchronization features:

•

The ADC12DJ4000RF uses a high-speed JESD204C

output interface with up to 16 serialized lanes

supporting up to 17.16 Gbps line rate. Deterministic

latency and multi-device synchronization is supported

through JESD204C subclass-1. The JESD204C

interface can be configured to trade-off line rate and

number of lanes. Both 8b/10b and 64b/66b data

encoding schemes are supported. 64b/66b encoding

supports forward error correction (FEC) for improved

bit error rates. The interface is backwards compatible

with JESD204B receivers.

•

– Automatic SYSREF timing calibration

– Timestamp for sample marking

JESD204C serial data interface:

Innovative

synchronization

features,

including

– Maximum lane rate: 17.16 Gbps

– Support for 64b/66b and 8b/10b encoding

– 8b/10b modes are JESD204B compatible

Optional digital down-converters (DDC):

– 4x, 8x, 16x and 32x complex decimation

– Four independent 32-Bit NCOs per DDC

Peak RF Input Power (Diff): +26.5 dBm (+ 27.5

dBFS, 560x fullscale power)

noiseless aperture delay adjustment and SYSREF

windowing, simplify system design for multi-channel

applications. Optional digital down converters (DDCs)

are available to provide digital conversion to

baseband and to reduce the interface rate. A

programmable FIR filter allows on-chip equalization.
