说明

ONET2804TLP 器件是一款用于并行光互联的高增益、限幅互阻抗放大器 (TIA),数据速率高达 28Gbps。此器件与 750μm 间距光电二极管阵列结合使用,可将光信号转换为差分输出电压。由内部电路提供光电二极管反向偏置电压并感测提供给各光电二极管的平均光电流。

该器件可配合引脚控制或两线制串口使用,从而实现对输出幅值、增益、带宽和输入阈值的控制。

ONET2804TLP 具有 17.5GHz 带宽、7.5kΩ 增益、2µArms 输入参考噪声和每通道的接收信号强度指示器 (RSSI)。通道间的 40dB 隔离可降低接收器中的串扰。

该器件需要单个 2.8V 至 3.3V 电源,每通道典型功耗为 90mW,差分输出幅度为 300 mVPP。该器件工作温度范围为 –40°C 至 +100°C,采用裸片形式,通道间距为 750μm。
