Precise Timing Protocol (PTP)
• Supports precise time stamping for packets, as
defined in IEEE 1588 PTP v1 and v2 and IEEE
802.1AS draft standards
• Supports Flexible Time Application interface to
distribute PTP clock and time to other devices in
the system
• Optionally accepts an external clock input for time
stamping
Audio Video Bridging networks
• Supports IEEE 802.1Qav draft Audio Video
Bridging networks
• Supports time- and priority-aware egress pacing
algorithm to prevent bunching and bursting
effects—suitable for audio/video applications
• Supports Egress Jitter Pacer for AVB-Class A and
AVB-Class B traffic and strict priority for legacy
traffic queues
USB 2.0 port
• Serves as a peripheral or host
• USB 2.0 compliant
• Integrated USB 2.0 PHY
• Enhanced Host Controller Interface (EHCI)
compatible as a host
• As a host, supports direct connection to all
peripheral types (LS, FS, HS)
• As a peripheral, connects to all host types (HS, FS)
and hubs
• Up to four independent endpoints, supporting
control, interrupt, bulk, and isochronous data
transfers
• Dedicated DMA for data movement between
memory and port
Two Integrated Marvell 3 Gbps (Gen2i) SATA PHYs
• Compliant with SATA II Phase 1 specifications
- Supports SATA II Native Command Queuing
(NCQ), up to 128 outstanding commands per
port
- Fully supports first party DMA (FPDMA)
- Backwards compatible with SATA I devices
• Supports SATA II Phase 2 advanced features
- 3 Gbps (Gen2i) SATA II speed
- Port Multiplier (PM)—Performs FIS-based
switching, as defined in SATA working group PM
definition
- Port Selector (PS)—Issues the protocol-based
Out-Of-Band (OOB) sequence for selecting the
active host port
• Supports device 48-bit addressing
• Supports ATA Tag Command Queuing
SATA II Host Controller
• Enhanced-DMA (EDMA) for the SATA ports
• Automatic command execution, without host
intervention
• Command queuing support, for up to 32
outstanding commands
• Separate SATA request/response queues
• 64-bit addressing support for descriptors and data
buffers in system memory

88F6281 controllers through their Serial-ATA ports,
enabling data communication between the
88F6281 controllers
• Advanced drive diagnostics via the ATA SMART
command
Cryptographic engine
• Hardware implementation on encryption and
authentication engines, to boost packet processing
speed
• Dedicated DMA to feed the hardware engines with
data from the internal SRAM memory or from the
DDR memory
• Implements AES, DES, and 3DES encryption
algorithms
• Implements SHA1 and MD5 authentication
algorithms
S/PDIF / I
2
S Audio In/Out interface
• Either S/PDIF or I
2
S inputs can be active at one
time
• Both S/PDIF and I
2
S outputs can be
simultaneously active, transferring the same PCM
data
