GFP-F
GFP Frame mode per ITU-T G.7041
GFP idle frame insertion and extraction
Supports Null and Linear headers
cHEC based frame delineation
X
CSF frame generation and detection
Error detection over core header and type headers
Programmable CRC-32 generation and verification
X.86 Support
Encapsulation Per ITU-T X.86 (Link Access Procedure for SONET/SDH), with 32 bit FCS
Transmit Transparency processing - 7E is replaced by 7D, 5E
Transmit Transparency processing – 7D replaced by 7D, 5D
Receive rate adaptation (7D, DD) removal.
Receive Transparency processing - 7D, 5E is replaced by 7D
Receive Transparency processing – 7D, 5D is replaced by 7D
Receive Abort Sequence - frame is dropped if 7D7E is detect
Selectable self-synchronizing X
Counters: Number of received valid frames and erred frames
Frame filtering due to bad Address/Control/SAPI, FCS error, abort, or frame length errors
DDR SDRAM Interface
16-bit wide data bus with dual edge transfers and Auto Refresh Timing
Designed to interface with 256Mbit JEDEC JESD79D compliant DDR SDRAMs with a 16-bit data bus
Addressable memory range up to 256 Mbits
JESD79D compliant device sizes other than 256 Mbits may be used, limited to 256 Mbit utilization
Compatible with DDR266+
SDRAM Interface Clock output of 125MHz
Direct connection to external DDR SDRAM (P2P Mode Support)
Example devices: Micron MT46V16M16, Samsung K4H561638F and Hynix HY5DU561622CF
MAC Interfaces
Two E/FE MAC ports with MII/RMII or one GbE port with GMII.
10Mbps/100Mbps/1000Mbps Data rates
Configurable for DTE or DCE mode
Facilitates auto-negotiation by host microprocessor
Programmable half and full-duplex modes
Flow control per 802.3 half-duplex (back-pressure) and full-duplex (pause) modes
Auto Negotiation for Rates and duplex modes
Programmable max MAC frame Lengths up to 2016 Bytes for E/FE, 12KB for GbE.
Minimum MAC frame length: 64 bytes
Discards frames larger than the max MAC frame size, Runt, non-octet bounded, or bad-FCS frames upon
reception
Programmable threshold for SDRAM queues to initiate flow control, with status indication
Terminal and Facility Loopbacks at MAC port (without SA/DA swapping)
Ethernet management interface (MDIO)
Supports all applicable RMON (RFC2819) 32 bit counters with saturation at max count.
Configurable for promiscuous mode and broadcast-discard mode.
