• Supports 16-bit MPI data path at 33 MHz
• Geared toward low cost applications
• Supports multiple families of microprocessors
3.10 Transmit and Receive UTOPIA
• Complete compliance with UTOPIA Level 2 Version 1.0 specifications for Multi-PHY (MPHY)
• Four UTOPIA ports with separate 4-cell rate matching buffers
• 50-MHz operation
• 16-bit wide data path
• MPHY operation with single TxCLAV and RxCLAV status signals
• Support of 52-byte and 53-byte cells
• Discarding of runt cells
• Optional discarding of cells with parity errors on transmit side
• Parity computation on receive side
