4 / 119 page Lattice Semiconductor ORCA ORT42G5 and ORT82G5 Data Sheet 4 Embedded Function Features • High-speed SERDES with programmable serial data rates over the range 0.6 to 3.7 Gbps. Operation has been demonstrated on design tolerance devices at 3.7 Gbps across 26 in. of FR-4 backplane and at 3.125 Gbps across 40 in. of FR-4 backplane across temperature and voltage specifications. • Asynchronous operation per receive channel with the receiver frequency tolerance based on one reference clock per block channels (separate PLL per channel). • Ability to select full-rate or half-rate operation per transmit or receive channel by setting the appropriate control registers. • Programmable one-half amplitude transmit mode for reduced power in chip-to-chip application. • Transmit preemphasis (programmable) for improved receive data eye opening. • 32-bit (8b/10b) or 40-bit (raw data) parallel internal bus for data processing in FPGA logic. • Provides a 10 Gbps backplane interface to switch fabric. Also supports multiple port cards at 2.5 Gbps. • 3.125 Gbps SERDES compliant with XAUI serial data specification for 10 G Ethernet applications with protec- tion. • IEEE 802.3ae compliant XAUI transceiver. Includes embedded IEEE 802.3ae-based XAUI link state machine. • Compliant to FC-0 specification for 1 Gbps, 2Gbps, 10 Gbps (FC-XAUI) modes. Includes Fibre Channel link state machine. • High-Speed Interface (HSI) function for clock/data recovery serial backplane data transfer without external clocks. • SERDES has low-power CML buffers. Support for 1.5V/1.8V I/Os. Allows use with optical transceiver, coaxial copper media, shielded twisted pair wiring or high-speed backplanes such as FR-4. • Power down option of SERDES HSI receiver or transmitter on a per-channel basis. • Automatic lock to reference clock in the absence of valid receive data. • High-speed and low-speed loopback test modes. • Requires no external component for clock recovery and frequency synthesis. • SERDES characterization pins available to control/monitor the internal interface to one SERDES block (ORT82G5 only). • SERDES HSI automatically recovers from loss-of-clock once its reference clock returns to normal operating state. • Built-in boundary scan (IEEE ® 1149.1 and 1149.2 JTAG) for the programmable I/Os, not including the SERDES interface. • FIFOs can align incoming data either across all eight channels (ORT82G5 only), across one or two groups of four channels, or across two or four groups of two channels. Alignment is done either using comma characters or by using the /A/ character in XAUI mode. Optionally, the alignment FIFOs can be bypassed for asynchronous operation between channels. (Each channel includes its own clock and frame pulse or comma detect.) • Addition of two 4K x 36 dual-port RAMs with access to the programmable logic. • The ORT82G5 is pinout compatible to the ORCA ORSO82G5 SONET backplane driver FPSC. The ORT42G5 is pin compatible to the ORSO42G5. |
