CH482D

CH482 is a QPDT broadband, high-speed bidirectional analog switch chip, including two differential channels of 2:1 MUX (four channels selectable for one). CH482D can be used for dual-channel differential signal selection, including USB 3.0 Super Speed, PCIe Gen1/2, SATA/SAS 1.5G/3G/6G, DisplayPort, and more.

CH482X shares similar functionalities with CH482D, but with higher bandwidth. It is suitable for dual-channel differential signal selection, including USB 3.1 Gen2 (USB 3.0 Super Speed+), PCIe Gen1/2/3, SATA/SAS 3G/6G, DisplayPort, and other applications.

Features:

• High bandwidth, with SuperSpeed channels supporting 6Gbps differential signals and compatibility with ultra-speed USB signals.
• CH482X SuperSpeed channels supporting 10Gbps differential signals and compatibility with USB 3.2 Gen2 signals.
• High-Speed (HS) channels supporting 1.5G (4:1) or 2.5Gbps (2:1) differential signals, accommodating full-scale voltage analog signals.
• HS channels supporting video signals and compatibility with low-speed, full-speed, and high-speed USB signals.
• Low ON resistance, with a typical Ron value of approximately 4Ω.
• Low crosstalk, high isolation.
• Global enable pin provided for unified enablement and switching of multi-channel analog switches.
• SuperSpeed channels ESD protection supporting 2KV HBM, while other channels and control pins have ESD protection supporting 4KV HBM.
• Supports rated 3.3V power supply voltage with low static power consumption.
• Available in various package forms such as QFN20-2.54.5, QFN42-3.59, and QFN28, and is compatible with RoHS.

Note:

1. The QFN package has the bottom pad marked as pin 0; it is not mandatory but recommended to connect.
2. CH483X is reserved for compatibility applications; for new designs, it is recommended to prioritize CH483M or CH482D.
