Introduction

AI Translation

CH315G/D is a USB extender control chip for real-time USB signal relay and transmission distance extension. CH315H is a USB signal isolation control chip for photoelectric or magnetic isolation of the USB bus. CH315 supports full-speed and low-speed USB transmission with hot-plug capability. The chip can be powered directly from the USB bus, supporting 5V or 3.3V supply voltage. CH315G/D is compatible with Cat 5 or Cat 5e UTP cable; transmission distance depends on cable quality, with a minimum of 200 meters for low-speed USB and 75 meters for full-speed USB. CH315H supports high-speed optocouplers or magnetic couplers, with isolation voltage determined by the isolator. The solution is purely hardware-based, fully transparent to the USB protocol, requires no additional drivers, and supports automatic detection of USB speed and device connection status.

Features

  • Supports 12Mbps full-speed USB and 1.5Mbps low-speed USB transmission, compatible with USB V2.0.
  • Supports USB control transfer, bulk transfer, interrupt transfer, and isochronous transfer.
  • Auto-detects USB full-speed or low-speed mode.
  • Configurable as host mode or device mode on the same chip, connecting to USB host and USB device respectively.
  • Device mode auto-detects USB device connection and disconnection; host mode auto-emulates USB device connection and disconnection.
  • Built-in impedance matching series resistors for USB signal lines, pull-up resistors for USB device side, and pull-down resistors for USB host side.
  • Built-in PLL and 12MHz USB clock; no external crystal or oscillator required, minimizing peripheral circuitry.
  • Pure hardware solution, fully real-time and transparent to USB protocol; no driver installation required; supports Windows, Linux, Android, and other operating systems.
  • Built-in 3.3V voltage regulator; supports 5V and 3.3V supply voltage.
  • Available in SOP14, QFN20, and SOP18 lead-free packages, RoHS compliant.
