SATA 3.0 Bridge Controller

• OOB Control is responsible for controlling OOB Signaling, Speed Negotiation
• Transceiver PHY performs the following functions:
• Converts 32-bit parallel data to differential Tx data and received Rx serial data to 32-bit parallel data
• Clock recovery from serial data
• 8B/10B encoding and decoding
• Line-rate change
• Out-of-Band (OOB) signal generation and detection
• Provide status to link layer

Link Layer

• Consists of Link layer FSM, CRC generator & Scrambler
• Scrambles / De-Scrambles
• CRC Calculations
• Adds/removes the frame envelope and extracts the useful contents of the FIS and passes on for further processing
• Handles flow control and transmission & reception errors

Bridge Layer

• Bridging b/w SATA Device Link layer & SATA Host Link layer
• command extraction logic
• FIS Extraction logic
• Customizable encryption /decryption logic
