Microchip OS81110 cPhy Evaluation Board (B20002)

OS81110 cPhy Evaluation Board (B20002) - a complete MOST150 Network device, utilizing the OS81110 Intelligent Network Interface Controller (INIC) device and the OS82150 MOST150 Coaxial Transceiver device. An on-board PIC32MX795 External Host Controller (EHC) is available for development of custom application code or use of application code provided by Microchip. An integrated OS85650 I/O Companion Chip (IOC) provides I/O port expansion for additional application flexibility. The OS81110 cPhy Board also supports power management, controlled by the MPM85000 Automotive Power management Device (PwrMgr), a MOST specification compliant power management device.

Board Features
Primary hardware features of the Eval110 cPHY Board include:

• Integrated Intelligent Network Interface Controller (INIC)
• Integrated MOST150 Coaxial Transceiver for Coaxial Physical Layer (cPHY) interface to a MOST150 Network
• Integrated I/O Companion Chip (IOC), including DTCP coprocessor
• Integrated External Host Controller (EHC), supporting:
  • Dual-wire CAN interface in conjunction with on-board MCP2562 [24] CAN transceiver
  • USB host functionality with connection to external device(s) using standard Type A receptacle
  • UART connection to on-board MCP2200 [29] CommBridge (for USB debug print terminal output on PC)
• Feature set expansion via Daughter Board and Auxiliary connectors supporting additional application options (e.g. video sourcing/sinking and low frequency signal tunneling)
• Stereo audio capabilities (via INIC or IOC Streaming Port), supporting:
  • sourcing stereo audio to the network from an on-board line-level input jack, and
  • sinking stereo audio from the network and driving an on-board headphone jack
• MOST Network-compliant power management capabilities, including:
  • Network activity detection
  • Control of switched application power regulators (3.3 V and 1.8 V supplies)
  • Continuous 3.3 V power supply
  • EHC Reset generator based on 3.3 V switched power
  • INIC and IOC reset generator, powered by 3.3V switched power, conditional on 1.8V switched power
  • Support for Sleep Power State with very low quiescent current
  • INIC power management, including voltage level reporting per levels defined in the MOST Specification 3.0
  • Support for wakeup signaling and MOST System Test via MOST Electrical Control Line [8]
  • Serial interface for configuration and status information
