•Supports proprietary 200 Mbps Marvell MII (MMII) interface

•Supports four modes:

-Port 0 RGMII, Port 1 RGMII

-Port 0 RGMII, Port 1 MII/MMII

-Port 0 MII/MMII, port 1 RGMII

-Port 0 GMII, Port 1 N/A

•DA filtering

„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

•Read ahead

•Advanced interrupt coalescing

•Target mode operation—supports attaching two 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 / I2S Audio In/Out interface

•Either S/PDIF or I2S inputs can be active at one time

•Both S/PDIF and I2S outputs can be simultaneously active, transferring the same PCM data

„S/PDIF-specific features

•Compliant with 60958-1, 60958-3, and IEC61937 specifications

•Sample rates of 44.1/48/96 kHz

•16/20/24-bit depths
