【产品】超高速模拟开关芯片 CH482/3/4/1/6,Ron典型值约为4Ω,支持额定3.3V电源电压
沁恒推出了CH482D、CH482X、CH483X、CH483M、CH484M、CH481D及CH486F超高速模拟开关芯片,这系列产品具有高带宽特性,SS 超速通道支持6Gbps差分信号,支持超速USB信号。
CH482是QPDT宽带超速双向模拟开关芯片,包含2个差分通道2:1 MUX(共4通道二选一),可用于USB3.0 Super Speed、PCIe Gen1/2、SATA/SAS 1.5G/3G/6G、Display Port等2路差分信号的二选一切换。
CH482X功能与CH482D类似,但带宽更高,可用于USB3.1 Gen2即 USB3.0 Super Speed+、PCIe Gen1/2/3、SATA/SAS 3G/6G、Display Port等2路差分信号的二选一切换。

CH483是QPDT宽带超速双向+DPDT宽带高速双向模拟开关芯片,包含3个差分通道2:1 MUX(共6通道二选一)。可用于USB3.0 Super Speed & USB2.0 High Speed、PCIe Gen1/2 & Refclk、Display Port等3路差分信号的二选一切换。
CH483X 相比CH483M主要有2 点区别:一是高速通道HS与超速通道SS完全独立,各自使用独立的控制信号;二是HS 通道的电源VCCH 额定是5V 电压,这种情况下,HS 通道支持5V 满幅信号并且控制信号支持5V 或3.3V。

【应用】国产CH482D超高速模拟开关用作USB3.0信号切换,最高支持6Gbps速率
该项目是为某公司定制的一块USB接口扩展卡,板卡功能是CPU通过PCIe接口扩展4个USB2.0接口和1个USB3.0接口。USB3.0用来作为高速通信接口,USB3.0接口采用TYPE-C设计,因为TYPE-C接口有两组USB3.0信号,要用模拟开关切换,笔者选用了沁恒公司的CH482D。
