TI DAC3XJ8X很低功耗电16位四路2.5 GSPS DAC解决方案

TI公司的DAC37J84/DAC38J84系列是非常低功耗16位四路1.6/2.5 GSPS DAC,其JESD204B接口高达12.5Gbps,最大输入数据速率1.23GSPS, 在2.5GSPS时的功耗为1.8W,主要用在基站,发送器,宽带通信,直接数字合成(DDS)仪表,毫米波/微波骨干网,自动测试设备(ATE)和有线通信等.本文介绍了DAC37J84/DAC38J84主要特性和框图, 评估模块DAC3XJ8XEVM主要特性和简化框图,电路图,材料清单和PCB元件布局图.

The pin-compatible DAC37J84/DAC38J84 family is a very low power, 16-bit, quad-channel, 1.6/2.5 GSPS digital to analog converter (DAC) with JESD204B interface up to 12.5 Gbps. The maximum input data rate is 1.23 GSPS. The DAC37J84/DAC38J84 family is also pin-compatible with the 16-bit, dual-channel, 1.6/2.5GSPS DAC37J82/DAC38J82 family.

Digital data is input to the device through 1, 2, 4 or 8 configurable serial JESD204B lanes running up to 12.5 Gbps with on-chip termination and programmable equalization. The interface allows JESD204B Subclass 1 SYSREF based deterministic latency and full synchronization of multiple devices.
