ADS52J91 具有LVDS、JESD 输出的10 位、12 位、14 位多通道低功耗

高速ADC

1 特性

3 说明

• 16 通道ADC，可配置为对8、16 或32 路

输入进行转换

• 最大ADC 转换速率：

– 10 位模式下为125MSPS

– 12 位模式下为100MSPS

– 14 位模式下为65MSPS

• 电源：1.2 V/1.8 V

ADS52J91 是一款低功耗、高性能、16 通道的模数转

换器 (ADC)。每个 ADC 在 10 位模式下的转换速率可

高达 125MSPS。ADC 分辨率越高，最高转换速率越

低。

该器件可配置为接受 8、16 或 32 个输入。在 32 位模

式下，每个 ADC 以值为 ADC 转换速率一半的有效采

样率对两个不同输入交替进行采样并转换。在 8 位输

入模式下，两个 ADC 以交错方式对同一输入进行转

换，这种情况下的有效采样率为 ADC 转换速率的 2

倍。ADC 设计为根据转换速率调整其功耗。

• 差分或单端输入时钟

• 信噪比(SNR)：

– 10 位模式下为61dBFS

– 12 位模式下为69dBFS

– 14 位模式下为73.5dBFS

5 说明（续）

ADC 输出会进行串行化，并与帧时钟和高速位时钟一起通过低压差分信令(LVDS) 接口输出。

该器件还具有一个可选的JESD204B 接口，同时可在16 输入和32 输入模式下工作。该接口的运行速率最高可达

5Gbps

该器件采用间距为0.8mm 的9mm × 15mm NFBGA-198 封装

right corner, click on Alert me to register and receive a weekly digest of any product information that has

changed. For change details, review the revision history included in any revised document.

6.3 Support Resources

TI E2E^™support forums are an engineer's go-to source for fast, verified answers and design help — straight

from the experts. Search existing answers or ask your own question to get the quick design help you need.

Linked content is provided "AS IS" by the respective contributors. They do not constitute TI specifications and do

not necessarily reflect TI's views; see TI's Terms of Use.

6.4 Trademarks

6.5 Electrostatic Discharge Caution

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled

with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may

be more susceptible to damage because very small parametric changes could cause the device not to meet its published

specifications.

⁽¹⁾The marketing status values are defined as follows:

ACTIVE: Product device recommended for new designs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.

OBSOLETE: TI has discontinued the production of the device.

⁽²⁾RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance

do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may

reference these types of products as "Pb-Free".

RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.

Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based

flame retardants must also meet the <=1000ppm threshold requirement.

⁽³⁾MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

⁽⁴⁾There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

⁽⁵⁾Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation

of the previous line and the two combined represent the entire Device Marking for that device.
