LTC2977 是一款 8 通道电源系统管理器，用于排序、修整 (伺服)、裕度调节、监控、管理故障、提供远端采样和创建故障记录。PMBus 命令支持电源排序、精准负载点电压调节和裕度调节。DAC 采用一种专有软连接算法以较大限度地抑制电源扰动。监控功能包括针对 8 个电源输出通道和一个电源输入通道上的过压和欠压门限限值，以及过温和欠温限值。可编程故障响应能够利用“在检测到故障之后执行重试操作”的选项来停用电源。导致电源停用的故障会自动触发黑匣子 EEPROM 存储器记录故障状态及相关的远端采样。一个内部 16 位 ADC 负责监视 8 个输出电压、1 个输入电压和芯片温度。此外，奇数通道还可配置以测量一个电流检测电阻器两端的电压。一个可编程看门狗定时器用于监视微处理器运作的失速状态，并在必要时使微处理器复位。单线式总线可在多个 LTC 电源系统管理 (PSM) 器件上实现同步。配置 EEPROM 支持自主型操作，并不需要额外的软件。

产品详情

The ADXBAND16EBZ contains four AD9084 mixed‑signal front‑end devices, including the RF front end, clocking, and power circuitry. The ADXBAND16EBZ serves as a complete system solution targeting common applications such as phased‑array radars, wideband systems, and ground‑based SATCOM. Its primary target application is a 16‑Tx/16‑Rx direct X‑band sampling phased array.

The platform is intended as a testbed for demonstrating multi‑chip synchronization, as well as implementing system‑level calibrations, beamforming algorithms, and other signal‑processing techniques. The system is designed to interface with the VCU118 Evaluation Board from Xilinx®, which features the Virtex® UltraScale+™ XCVU9P FPGA, along with provided reference software, HDL code, and MATLAB system‑level interfaces.

A 16‑Tx/16‑Rx Calibration Board can be used to develop system‑level calibration algorithms, including demonstrations of power‑up phase determinism. The Calibration Board provides improvements in combined‑channel dynamic range, spurious performance, and phase noise, and can be controlled via a MATLAB add‑on when connected to the PMOD interface of the VCU118.
