AD8302是一款完全集成式系统,用于测量多种接收、发射和仪器仪表应用中的增益/损耗和相位。它只需极少的外部元件,采用2.7 V至5.5 V单电源供电。在50 Ω系统中,交流耦合输入信号范围为–60 dBm至0 dBm,低频高达2.7 GHz。这些输出在±30 dB的范围内提供精确的增益或损耗测量,调整比例为30 mV/dB,相位范围为0°–180°,调整比例为10 mV/度。两个子系统都具有30 MHz的输出带宽,可通过增加外部滤波器电容来降低该带宽。AD8302可在控制器模式下使用,驱动信号链的增益和相位达到预定设定点。 AD8302包括一对紧密匹配的解调对数放大器,每个放大器具有60 dB测量范围。通过提取其输出之差,可测量两个输入信号之间的幅值比或增益。这些信号甚至处于不同的频率下,以便测量转换增益或损耗。通过在一个输入上施加未知信号并在另一个输入上施加校准的交流基准信号,AD8302可用于确定绝对信号电平。通过禁用输出级反馈连接,可使用设定点引脚MSET和PSET实现比较器,从而设置阈值。 信号输入采用单端模式,可将其直接匹配并连接到定向耦合器。在低频下,其输入阻抗为3

BCM5461S详细设计开发资料。 BCM5461S SUPPORTED SWITCH/MAC INTERFACES: • GMII (Gigabit Media Independent Interface): 1000-Mbps data rate (designed for 2.5V or 3.3V I/O operation) • MII (Media Independent Interface): 100/10-Mbps data rates (designed for 2.5V or 3.3V I/O operation) • RGMII (Reduced pin count version of GMII): (1000/100/10-Mbps operation with 2.5V I/Os) • TBI (10-Bit Interface) 1000-Mbps operation • RTBI (Reduced pin count version of Ten Bit Interface): 1000-Mbps operation with 2.5V I/Os) • SGMII (Serial GMII): 1000/100/10 The BCM5461S is an unshielded twisted pair (UTP) Gigabit Ethernet transceiver that features an on-chip 1.25-Gbaud IEEEcompliant SerDes interface. This device employs advanced digital signal processing techniques to deliver the highest transmission and reception performance in the industry while allowing fabrication in low-power, low-cost 1.2V CMOS technology. The BCM5461S copper interface provides 10/100/1000BASE-T transmission and reception with autonegotiation. The 1.25-Gbaud serial interface can be configured for interfacing to a fiber optical module, a SerDes-compatible device, or an SGMII MAC interface. The serial interface is robust enough to use in backplane FR4 applications. This document summarizes the test conditions and results of backplane signaling evaluation, as well as the receive jitter tolerance evaluation for the BCM5461S SerDes interface.
