Texas Instruments ADS52J90ZZE

Overview

ADS52J90ZZE from Texas Instruments is a 16-channel, multibit analog-to-digital converter (ADC) supporting configurable 8/16/32-input modes with resolution options of 10-, 12-, or 14-bit. It achieves up to 100 MSPS in 10-bit mode, delivers 61–73.5 dBFS SNR across resolutions, and uses LVDS serialization for high-speed data output. It targets ultrasound imaging front-ends requiring low-power, high-channel-count digitization.

For engineers reviewing the ADS52J90ZZE datasheet, ADS52J90ZZE pinout, ADS52J90ZZE application, or ADS52J90ZZE equivalent, key selection considerations include input configuration flexibility (8/16/32 inputs), resolution–speed trade-offs (100/80/65 MSPS), LVDS serialization ratio (10X–16X), power scaling per channel (41 mW at 100 MSPS), and NFBGA-198 thermal/mechanical compatibility.

Technical Context

The ADS52J90ZZE implements 16 independent ADC cores with programmable interleaving logic: in 32-input mode, each core alternately samples two inputs at half the conversion rate; in 8-input mode, two cores interleave on one input to double effective sampling rate. Clocking supports differential or single-ended inputs with dedicated FCLKP/FCLKM and DCLKP/DCLKM pairs.

Digital processing includes on-chip LVDS serializer with selectable 10X/12X/14X/16X serialization ratios, frame clock (FCLK) and bit clock (DCLK) outputs, and serial interface (SEN/SCLK/SDIN/SDOUT) for configuration. Power domains are segregated: AVDD_1P8 and AVSS for analog, DVDD_1P2/DVDD_1P8 and DVSS for digital/LVDS, enabling independent supply optimization.

Key Specifications

Pinout & Package

The ADS52J90ZZE is housed in a 9.0 mm × 15.0 mm, 0.8-mm pitch NFBGA-198 package with exposed thermal pad. Pin functions are defined per TI SBAS690A Rev A (June 2015), including dual clock inputs (CLKP/CLKM, FCLKP/FCLKM), 32 analog inputs (INP1–INP32, INM1–INM32), 32 LVDS output pairs (DOUTP1/DOUTM1 through DOUTP16/DOUTM16), and dedicated serial control (SEN, SCLK, SDIN, SDOUT).

FAQ

What resolution and sampling rate combinations does the ADS52J90ZZE support?

The ADS52J90ZZE supports three discrete resolution–rate pairings: 10-bit at up to 100 MSPS, 12-bit at up to 80 MSPS, and 14-bit at up to 65 MSPS. These are hard-coded operating modes - no interpolation or oversampling is performed. Each mode delivers corresponding SNR values of 61 dBFS, 70 dBFS, and 73.5 dBFS respectively, as measured under standard test conditions per SBAS690A.

How does the ADS52J90ZZE handle 32-input configuration with only 16 ADC cores?

The ADS52J90ZZE achieves 32-input operation by time-interleaving its 16 ADC cores: each core alternately samples two distinct analog inputs, resulting in an effective sampling rate that is half the ADC conversion rate. This architecture maintains full 16-channel parallel output timing while doubling input channel count without increasing core count or power proportionally.

What are the voltage and sequencing requirements for ADS52J90ZZE supplies?

The ADS52J90ZZE requires three independent supplies: AVDD_1P8 (1.8 V, analog), DVDD_1P2 (1.2 V, digital logic), and DVDD_1P8 (1.8 V, LVDS drivers). Per SBAS690A, AVDD_1P8 must be powered first and ramped monotonically; DVDD_1P2 and DVDD_1P8 may be powered simultaneously but must stabilize before RESET release. Undervoltage lockout is not integrated - external supervisors are recommended.

Can the ADS52J90ZZE LVDS outputs interface directly with Xilinx Artix-7 FPGA banks?

Yes, the ADS52J90ZZE LVDS outputs comply with ANSI TIA/EIA-644-A and are compatible with Xilinx Artix-7 HP bank LVDS_25 I/O standards. The device supports 10X–16X serialization, allowing mapping to 10–16 differential pairs. FCLK and DCLK outputs provide deterministic phase alignment for IDELAYE2 calibration, and setup/hold margins exceed 150 ps at 100 MSPS base rate.

Is the ADS52J90ZZE RoHS compliant and what is its moisture sensitivity level?

Yes, the ADS52J90ZZE is RoHS compliant (Pb-free, green) and carries an MSL Level-3 rating per JEDEC J-STD-020, with peak reflow temperature of 260°C and floor life of 168 hours at ≤30°C/60% RH. The device marking "ADS52J90" appears on the top surface, and packaging is JEDEC-standard tray (160 units per tray).
