AD9878BST集成电路（IC）的模拟前端（AFE）规格书PDF中文资料

AD9878BST属于集成电路（IC）的模拟前端（AFE）。由亚德诺半导体技术有限公司制造生产的AD9878BST模拟前端（AFE）模拟前端 (AFE) 是一种用于信号调节的半导体器件，由模拟放大器、运算放大器、滤波器和集成电路构成。这种可配置功能块能连接各种传感器。分辨率范围从 8 位至 42 位不等，通道数范围为 1 至 256 个。

GENERAL DESCRIPTION

The AD9878 is a single-supply, cable modem/set-top box, mixed-signal front end. The device contains a transmit path interpolation filter, a complete quadrature digital upconverter, and a transmit DAC. The receive path contains dual 12-bit ADCs and a 10-bit ADC. All internally required clocks and an output system clock are generated by the phase-locked loop (PLL) from a single crystal oscillator or clock input.
