The ispGDX2 family is available in two options. The standard device supports sysHSI capability for ultra fast serial communications while the lower-cost “E-series” supports the same high-performance FPGA fabric without the sysHSI Block. This family of switches combines a flexible switching architecture with advanced sysIO interfaces including high performance sysHSI Blocks, and sysCLOCK PLLs to meet the needs of the today’s high-speed systems. Through a muliplexer-intensive architecture, the ispGDX2 facilitates a variety of common switching functions. The availability of on-chip control logic further enhances the power of these devices. A high-performance solution, the family supports bandwidth up to 38Gbps. Every device in the family has a number of PLLs to provide the system designer with the ability to generate multiple clocks and manage clock skews in their systems. 2 Lattice Semiconductor ispGDX2 Family Data Sheet The sysIO interfaces provide system-level performance and integration. These I/Os support various modes of LVCMOS/LVTTL and support popular high-speed standard interfaces such as GTL+, PCI-X, HSTL, SSTL, LVDS and Bus-LVDS. The sysHSI Blocks further extend this capability by providing high speed serial data transfer capability. SE L D E IS C C T O D N E TI VI N C U E ED S Devices in the family can operate at 3.3V, 2.5V or 1.8V core voltages and can be programmed in-system via an IEEE 1149.1 interface that is compliant with the IEEE 1532 standard. Voltages required for the I/O buffers are independent of the core voltage supply. This further enhances the flexibility of this family in system designs. Typical applications for the ispGDX2 include multi-port multi-processor interfaces, wide data and address bus multiplexing, programmable control signal routing and programmable bus interfaces. Table 1 shows the members of the ispGDX2 family and their key features. Architecture The ispGDX2 devices consist of GDX Blocks interconnected by a Global Routing Pool (GRP). Signals interface with the external system via sysIO banks. In addition, each GDX Block is associated with a FIFO and a sysHSI Block to facilitate the transfer of data on- and off-chip. Figure 1 shows the ispGDX2 block diagram. Each GDX Block can be individually configured in one of four modes: • Basic (No FIFO or SERDES) • FIFO Only • SERDES Only • SERDES and FIFO Each sysIO bank has its own I/O power supply and reference voltage. Designers can use any output standard within a bank that is compatible with the power supply. Any input standard may be used, providing it is compatible with the reference voltage. The banks are independent. Global Routing Pool (GRP) The ispGDX2 architecture is organized into GDX Blocks, which are connected via a Global Routing Pool. The innovative GRP is optimized for routability, flexibility and speed. All the signals enter via the GDX Block. The block supplies these either directly or in registered form to the GRP. The GRP routes the signals to different blocks, and provides separate data and control routing. The data path is optimized to achieve faster speed and routing flexibility for nibble oriented signals. The control routing is optimized to provide high-speed bit oriented routing of control signals. There are some restrictions on the allocation of pins for optimal bus routing. These restrictions are considered by the software in the allocation of pins. GDX Block The blocks are organized in a “block” (nibble) manner, with each GDX Block providing data flow and control logic for 16 I/O buffers. The data flow is organized as four nibbles, each nibble containing four Multiplexer Register Blocks (MRBs). Data for the MRBs is provided from 64 lines from the GRP. Figure 2 illustrates the groups of signals going into and out of a GDX Block. Control signals for the MRBs are provided from the Control Array. The Control Array receives the 32 signals from the GRP and generates 16 control signals: eight MUX Select, four Clock/Clock Enable, two Set/Reset and two Output Enable. Each nibble is controlled via two MUX select signals. The remaining control signals go to all the MRBs. Besides the control signals from the Control Array, the following global signals are available to the MRBs in each GDX Block: four Clock/Clock Enable, one reset/preset, one power-on reset, two of four MUX select (two of two in 64 I/O), four Output Enable (two in 64 I/O) and Test Out Enable (TOE). 3 Lattice Semiconductor ispGDX2 Family Data Sheet MUX and Register Block (MRB) Every MRB Block has a 4:1 MUX (I/O MUX) and a set of three registers which are connected to the I/O buffers, FIFO and sysHSI Blocks. Multiple MRBs can be combined to form large multiplexers as described below. Figure 3 shows the structure of the MRB. SE L D E IS C C T O D N E TI VI N C U E ED S Each of the three registers in the MRB can be configured as edge-triggered D-type flip-flop or as a level sensitive latch. One register operates on the input data, the other output data and the last register synchronizes the output enable function. The input and output data signals can bypass each of their registers. The polarity of the data out and output enable signals can be selected. The Output and OE register share the same clock and clock enable signals. The Input register has a separate clock and clock enable. The initialization signals of each register can be independently configured as Set or Reset. These registers have programmable polarity control for Clock, Clock Enable and Set/Reset. The output enable register input can be set either by one of the two output enables generated locally from the Control Array or from one of the four (two in 64 I/O) Global OE enable pins. In addition to the local clock and clock enable signals, each MRB has access to Global Clock, Clock Enable, Reset and TOE nets. 4 Lattice Semiconductor ispGDX2 Family Data Sheet Figure 2.

Each output register corresponding to MRB “n”, receives data output from its two adjacent MRBs, MRB (n-1) and MRB (n+1), to provide shift register capability. Like the output register, each input register of the MRB has built-in shift register capability. Each input register can receive data from its two adjacent MRB input registers, to provide bi-directional shift register capability. The chaining crosses GDX Block boundaries. The chain of input registers and the chain of output registers can be combined as one shift register via the GRP. 5 Lattice Semiconductor ispGDX2 Family Data Sheet The four data inputs to the 4:1 MUX come from the GRP. The output of this MUX connects to the output register. A fast feedback path from the MUX to the GRP allows wider MUXes to be built. Table 2 summarizes the various MUX sizes and delay levels.

The true and complement forms of 32 inputs from the GRP are available in the control array. The 20 NAND terms can use any or all of these inputs to form the control array outputs. Two AND terms are combined with a NOR term to form Set/Reset and OE signals. Figure 4 illustrates the control array. 6 Lattice Semiconductor ispGDX2 Family Data Sheet Figure 4. ispGDX2 Family Control Array 32 Inputs from Control GRP SE L D E IS C C T O D N E TI VI N C U E ED S Each connection is programmable.

To MRB Set/Reset To MRB Output Enable sysIO Banks The inputs and outputs of ispGDX2 devices are divided into eight sysIO banks, where each bank is capable of supporting different I/O standards. The number of I/Os per bank is 32, 16 and 8 for the 256-, 128- and 64-I/O devices respectively. Each sysIO bank has its own I/O supply voltage (VCCO) and reference voltage (VREF), allowing each bank complete independence from the other banks. Each I/O within a bank can be individually configured to any standard consistent with the VCCO and VREF settings. Figure 5 shows the I/O banks for the ispGDX2-256 device. The I/O of the ispGDX2 devices contain a programmable strength and slew rate tri-state output buffer, a programmable input buffer, a programmable pull-up resistor, a programmable pull-down resistor and a programmable buskeeper latch. These programmable capabilities allow the support of a wide range of I/O standards. 7 Lattice Semiconductor ispGDX2 Family Data Sheet Figure 5. ispGDX2-256 sysIO Banks SE L D E IS C C T O D N E TI VI N C U E ED S VCCO3 VREF3 GND VCCO4 VREF4 GND sysIO Bank 4 sysIO Bank 3 VCCO5 VREF5 VCCO2 sysIO Bank 5 sysIO Bank 2 VREF2 GND GND VCCO6 VCCO1 VREF6 sysIO Bank 6 sysIO Bank 1 GND VREF1 GND sysIO Bank 7 sysIO Bank 0 VCCO0 VREF0 GND VCCO7 VREF7 GND There are three classes of I/O interface standards implemented in the ispGDX2 devices. The first is the non-terminated, single-ended interface; it includes the 3.3V LVTTL standard along with the 1.8V, 2.5V and 3.3V LVCMOS interface standards. The slew rate and strength of these output buffers can be controlled individually. Additionally, PCI 3.3, PCI-X and AGP-1X are all subsets of this interface type. The second interface class implemented is the terminated, single-ended interface standard. This group of interfaces includes different versions of SSTL and HSTL interfaces along with CTT and GTL+. Use of these I/O interfaces requires an additional VREF signal. At the system level, a termination voltage, VTT, is also required. Typically, an output will be terminated to VTT at the receiving end of the transmission line it is driving. The final types of interfaces implemented are the differential standards LVPECL, LVDS and Bus LVDS. Table 3 shows the I/O standards supported by the ispGDX2 devices along with nominal VCCO, VREF and VTT. The ispGDX2 family also features 5V tolerant I/O. I/O banks with VCCO = 3.3V may have inputs driven to a maximum of 5.5V for easy interfacing with legacy systems. Up to 64 I/O pins per device may be driven by 5V inputs. 8 Lattice Semiconductor ispGDX2 Family Data Sheet Table 3. ispGDX2 Supported I/O Standards Nominal VCCO Nominal VREF Nominal VTT LVCMOS 3.3 3.3V — — LVCMOS 2.5 2.5V — — LVCMOS 1.8 1.8V — — LVTTL 3.3V — — PCI 3.3 3.3V — — PCI -X 3.3V — — AGP-1X 3.3V — — SSTL3 class I & II 3.3V 1.5V 1.5V SE L D E IS C C T O D N E TI VI N C U E ED S sysIO Standard SSTL2 class I & II 2.5V 1.25V 1.25V CTT 3.3 3.3V 1.5V 1.5V CTT 2.5 2.5V 1.25V 1.25V HSTL class I 1.5V 0.75V 0.75V HSTL class III 1.5V 0.9V 0.75V HSTL class IV 1.5V 0.9V 1.5V 1.8/2.5/3.3V 1.0V 1.5V 3.3V — — LVDS 2.5/3.3V — — Bus-LVDS 2.5/3.3V — — GTL+ LVPECL1, 2, 3 1.

For more information on the sysIO capability, please refer to Lattice technical note number TN1000, sysIO Design and Usage Guidelines. sysCLOCK PLL The sysCLOCK PLL circuitry consists of Phase-Lock Loops (PLLs) along the various dividers and reset and feedback signals associated with the PLLs. This feature gives the user the ability to synthesize clock frequencies and generate multiple clock signals for routing within the device. Furthermore, it can generate clock signals that are deskewed either at the board level or the device level. Figure 6 shows the ispGDX2 PLL block diagram. Each PLL has a set of PLL_RST, PLL_FBK and PLL_LOCK signals. In order to facilitate the multiply and divide capabilities of the PLL, each PLL has associated dividers. The M divider is used to divide the clock signal, while the 9 Lattice Semiconductor ispGDX2 Family Data Sheet SE L D E IS C C T O D N E TI VI N C U E ED S N divider is used to multiply the clock signal. The K divider is used to provide a divided clock frequency of the adjacent PLL. This output can be routed to the global clock net. The V divider is used to provide lower frequency output clocks, while maintaining a stable, high frequency output from the PLL’s VCO circuit. The PLL also has a delay feature that allows the output clock to be advanced or delayed to improve set-up and clock-to-out times for better performance. For more information on the PLL, please refer to Lattice technical note number TN1003, sysCLOCK PLL Design and Usage Guidelines.

These global clocks, CLK0-3, can either be generated by the PLL circuits or supplied externally. External clock pins can be configured as single-ended or differential (LVDS) input. Figure 7 illustrates how the sysCLOCK PLL inputs and outputs can be routed to the I/O pins or general routing. Figure 10 shows the clock network for the ispGDX2-256 and Figure 8 shows the clock networks for ispGDX2-128 and ispGDX2-64. The Reset (0) pin from the Control Array of selected GDX Blocks can be programmed to reset the M Divider of the PLLs. This provides a means for generating the reset signal internally.

In basic mode, the SERDES and FIFO are disabled and the MUX output of the MRB connects to the output register. Inputs are connected to the GRP via the MRB. SE L D E IS C C T O D N E TI VI N C U E ED S Figure 11 shows the four different operating modes. Precise detail of the FIFO and SERDES connections is provided in their respective sections. Figure 11.

FIFO Operations Each GDX Block is associated with a 10-bit wide and 15-word deep (10x15) RAM. This RAM, combined with two address counters and two comparators, is used to implement a FIFO as a “circular queue”. The FIFO has separate clocks, the Read Clock (RCLK) and Write Clock (WCLK), for asynchronous operation. The FIFO has three additional control signals Write Enable, Read Enable and FIFO Reset. Three flags show the status of the FIFO: Empty, Full and Start Read. Each FIFO receives the global Power-on Reset and Reset signals. Figure 12 shows the connections to the FIFO. 14 Lattice Semiconductor ispGDX2 Family Data Sheet Figure 12. ispGDX2 FIFO Signals 10 10 Data Out (DOUT) Data In (DIN) Write Clock (WCLK) SE L D E IS C C T O D N E TI VI N C U E ED S Write Enable (WE) Read Clock (RCLK) Read Enable (RE) FIFO 10x15 Full (FULL) Empty (EMPTY) Global Reset (RESETb) Start Read (STRDb) Power-on Reset (PORb) FIFO Reset (FIFORSTb) Read Clock and Read Enable are the same as the Clock and Clock Enable signals of the input registers of the associated MRB. These registers are used to register the FIFO outputs, and in modes that utilize the FIFO are configured to use the same clock and clock enable signals. The Write Clock is selected from one of the GCLK/CE signals or the RECCLK (Recovered Clock) signal from the associated SERDES. The Write Enable is selected from one of the local MRB product term CLK/CE signals. All FIFO operations occur on the rising edge of the clock although clock polarity of these signals can be programmed. The flags from the FIFO, FULL, EMPTY and STRDb (Start Read) are each fed via a MUX in the MRB to an I/O buffer. The STRDb (half full) signal is used in conjunction with SERDES. STRDb is an active low signal, the signal is inactive (high) on FIFO RESET. After the FIFO reset when the FIFO contains data in five memory locations, at the following write clock transition the STRDb becomes active (low). Note, if the Read Clocks arrive before writing the sixth location, it may take longer than five write clocks before the STRDb becomes active. When the FIFO has data in the first six locations, at the next write clock transition the STRDb becomes inactive (high). Again, if the Read Clocks arrive before writing the seventh location, the STRDb may stay active for longer than one write clock period, even if the FIFO contains data in less than five locations. After this event, the STRDb stays inactive until the FIFO is RESET again. STRDb does not become active again even if less than six memory locations are occupied in the FIFO. It is the user’s responsibility to monitor the FULL and EMPTY signals to avoid data underflow/overflow and to take appropriate actions. Figure 13 shows how the FIFO is connected between the I/O banks and the GDX Blocks in FIFO mode. For more information on the FIFO, please refer to Lattice technical note number TN1020, sysHSI Usage Guidelines. 15 Lattice Semiconductor ispGDX2 Family Data Sheet Figure 13.

The ispGDX2 devices have multiple sysHSI Blocks. SE L D E IS C C T O D N E TI VI N C U E ED S Each sysHSI Block has two SERDES blocks which contain two main sub-blocks, Transmitter (with a serializer) and Receiver (with a deserializer) including Clock/Data Recovery Circuit (CDR). Each SERDES can be used as a full duplex channel. The two SERDES in a given sysHSI Block share a common clock and must operate at the same nominal frequency. Figure 14 shows the sysHSI Block. Device features support two data coding modes: 10B/12B and 8B/10B (for use with other encoding schemes, see Lattice’s sysHSI application notes). The encoding and decoding of the 10B/12B standard are performed within the device in dedicated logic. For the 8B/10B standard, the symbol boundaries are aligned internally but the encoding and decoding are performed outside the device. Each SERDES block receives a single high speed serial data input stream (with embedded clock) from an input, and provide a low speed 10-bit wide data stream and a recovered clock to the device. For transmitting, the SERDES converts a 10-bit wide low-speed data stream to a single high-speed data stream with embedded clock for output. Additionally, multiple sysHSI Blocks can be grouped together to form a source synchronous interface of between 18 channels. Figure 15 shows the connections of the SERDES block with the FIFO, sysIO block and the MRB. Table 6 provides the descriptions of the SERDES. For more information on the SERDES/CDR, refer to Lattice technical note number TN1020, sysHSI Usage Guidelines. Table 6.

This allows functional testing of the circuit board on which the device is mounted through a serial scan path that can access all critical logic notes. Internal registers are linked internally, allowing test data to be shifted in and loaded directly onto test nodes, or test node data to be captured and shifted out for verification. In addition, these devices can be linked into a board-level serial scan path for more board-level testing. The test access port has its own supply voltage that can operate with LVCMOS3.3, 2.5 and 1.8 standards. sysIO Quick Configuration To facilitate the most efficient board test, the physical nature of the I/O cells must be set before running any continuity tests. As these tests are fast, by nature, the overhead and time that is required for configuration of the I/Os' physical nature should be minimal so that board test time is minimized. The ispGDX2 family of devices allows this by offering the user the ability to quickly configure the physical nature of the sysIO cells. This quick configuration takes milliseconds to complete, whereas it takes seconds for the entire device to be programmed. Lattice's ispVM™ System programming software can either perform the quick configuration through the PC parallel port, or can generate the ATE or test vectors necessary for a third-party test system. IEEE 1532-Compliant In-System Programming In-system programming of devices provides a number of significant benefits including rapid prototyping, lower inventory levels, higher quality and the ability to make in-field modifications. All ispGDX2 devices provide In-System Programming (ISP) capability through their Boundary Scan Test Access Port. This capability has been implemented in a manner that ensures that the port remains compliant to the IEEE 1532 standard. By using IEEE 1532 as the communication interface through which ISP is achieved, designers get the benefit of a standard, well defined interface. The ispGDX2 devices can be programmed across the commercial temperature and voltage range. The PC-based Lattice software facilitates in-system programming of ispGDX2 devices. The software takes the JEDEC file output produced by the design implementation software, along with information about the scan chain, and creates a set of vectors used to drive the scan chain. The software can use these vectors to drive a scan chain via the parallel port of a PC. Alternatively, the software can output files in formats understood by common automated test equipment. This equipment can then be used to program ispGDX2 devices during the testing of a circuit board. Security Scheme A programmable security scheme is provided on the ispGDX2 devices as a deterrent to unauthorized copying of the array configuration patterns. Once programmed, this scheme prevents readback of the programmed pattern by a device programmer, securing proprietary designs from competitors. The security scheme also prevents programming and verification. The entire device must be erased in order to reset the security scheme. Hot Socketing The ispGDX2 devices are well suited for those applications that require hot socketing capability. Hot socketing a device requires that the device, when powered down, can tolerate active signals on the I/Os and inputs without being damaged. Additionally, it requires that the effects of the powered-down device be minimal on active signals. 21 Lattice Semiconductor ispGDX2 Family Data Sheet Absolute Maximum Ratings 1, 2, 3 ispGDX2C (1.8V) ispGDX2B/V (2.5/3.3V) Supply Voltage VCC . . . . . . . . . . . . . . . . . . . . . . . . -0.5 to 2.5V . . . . . . . . . . . . . . . . -0.5 to 5.5V PLL Supply Voltage VCCP . . . . . . . . . . . . . . . . . . . . -0.5 to 2.5V . . . . . . . . . . . . . . . . -0.5 to 5.5V SE L D E IS C C T O D N E TI VI N C U E ED S Output Supply Voltage VCCO . . . . . . . . . . . . . . . . . -0.5 to 4.5V . . . . . . . . . . . . . . . . -0.5 to 4.5V JTAG Supply Voltage (VCCJ) . . . . . . . . . . . . . . . . . -0.5 to 4.5V . . . . . . . . . . . . . . . . -0.5 to 4.5V Input or I/O Tristate Voltage Applied 4, 5 . . . . . . . . . -0.5 to 5.5V . . . . . . . . . . . . . . . . -0.5 to 5.5V Storage Temperature . . . . . . . . . . . . . . . . . . . . . . . -65 to 150°C . . . . . . . . . . . . . . . -65 to 150°C Junction Temp.

The timing model provided in Figure 18 shows the specific delay paths. Once the implementation of a given function is determined either conceptually or from the software report file, the delay path of the function can easily be determined from the timing model. The Lattice design tools report the timing delays based on the same timing model for a particular design. Note that the internal timing parameters are given for reference only, and are not tested. The external timing parameters are tested and guaranteed for every device.

It provides guidance on a number of input parameters, including signal amplitude and rise time limits, noise and jitter limits, and P and N input skew tolerance.

Receive Data Eye Diagram Template (Differential) Bit Time V THD 200 mV Differential +/- 100 mV Single Ended jt TH eo SIN jtTH jtTH : Optimum Threshold Crossing Jitter The data pattern eye opening at the receive end of a link is considered the ultimate measure of received signal quality. Almost all detrimental characteristics of a transmit signal and the interconnection link design result in eye closure. This combined with the eye-opening limitations of the line receiver can provide a good indication of a link’s ability to transfer error-free data. Signal jitter is of special interest to system designers. It is often the primary limiting characteristic of long digital links and of systems with high noise level environments. An interesting characteristic of the clock and data recovery (CDR) portion of the ispGDX2 SERDES receiver is its ability to filter incoming signal jitter that is below the clock recovery PLL bandwidth. For signals with high levels of low frequency jitter, the receiver can detect incoming data error free, with eye openings significantly less than that shown in Figure 22. sysHSI Block AC Specifications Operating Frequency Ranges Symbol fCLK Description Mode Reference Clock Frequency Test Condition Min.

The signals in this column route to/from the assigned pins of the associated I/O cell. 2. The signals in this column use the I/O cell. If a receiver signal is present in the I/O cell, the associated pin is available for output only. When transmit data (TXD) is present in the cell, the associated pin is available for input only. 3. The DOUT outputs are routed to GRP through the input register of the cell and the DIN inputs are routed direct from the associated pins in FIFO only mode. In SERDES with FIFO mode, the FULL and EMPTY flags are routed to the associated pins through the output MUX and the pins. 4. If the Source Synchronous Receiver is used in the HSI Block, this pin is unavailable for another use and must be left unconnected. 5. The SYDT signal has two routing options. If direct output through the dedicated pin is used, the I/O cell (the whole HSI Block) is not available for transmitter. The SYDT in the I/O Cell column is routed to the GRP through the input register of the cell and frees the I/O cell for transmitter. 6. FIFO_STRDb flag output is used in SERDES with FIFO Mode only. 7. sysHSI Source Synchronous Receive Mode is not available for channel 1A. 55 Lattice Semiconductor ispGDX2 Family Data Sheet ispGDX2-128 Logic Signal Connections Signal Name sysIO LVDS Bank Pair/Polarity GDX Block MRB SERDES Mode I/O Pin1 SERDES Mode I/O Cell2 FIFO Mode I/O Cell/Pin3 208 fpBGA -

The signals in this column route to/from the assigned pins of the associated I/O cell. 2. The signals in this column use the I/O cell. If a receiver signal is present in the I/O cell, the associated pin is available for output only. When transmit data (TXD) is present in the cell, the associated pin is available for input only. 3. The DOUT outputs are routed to GRP through the input register of the cell and the DIN inputs are routed direct from the associated pins in FIFO only mode. In SERDES with FIFO mode, the FULL and EMPTY flags are routed to the associated pins through the output MUX and the pins. 4. If the Source Synchronous Receiver is used in the HSI Block, this pin is unavailable for another use and must be left unconnected. 5. The SYDT signal has two routing options. If direct output through the dedicated pin is used, the I/O cell (the whole HSI Block) is not available for transmitter. The SYDT in the I/O Cell column is routed to the GRP through the input register of the cell and frees the I/O cell for transmitter. 6. FIFO_STRDb flag output is used in SERDES with FIFO Mode only. 7. sysHSI Source Synchronous Receive Mode is not available for channel 1A. 59 Lattice Semiconductor ispGDX2 Family Data Sheet ispGDX2-256 Logic Signal Connections Signal Name sysIO Bank LVDS GDX Pair/Polarity Block MRB SERDES Mode I/O Pin1 SERDES Mode I/O Cell2 FIFO Mode I/O Cell/Pin3 484 fpBGA 0 0N 0A 0 -

The signals in this column route to/from the assigned pins of the associated I/O cell. 2. The signals in this column use the I/O cell. If a receiver signal is present in the I/O cell, the associated pin is available for output only. When transmit data (TXD) is present in the cell, the associated pin is available for input only. 3. The DOUT outputs are routed to GRP through the input register of the cell and the DIN inputs are routed direct from the associated pins in FIFO only mode. In SERDES with FIFO mode, the FULL and EMPTY flags are routed to the associated pins through the output MUX and the pins. 4. If the Source Synchronous Receiver is used in the HSI Block, this pin is unavailable for another use and must be left unconnected. 5. The SYDT signal has two routing options. If direct output through the dedicated pin is used, the I/O cell (the whole HSI Block) is not available for transmitter. The SYDT in the I/O Cell column is routed to the GRP through the input register of the cell and frees the I/O cell for transmitter. 6. FIFO_STRDb flag output is used in SERDES with FIFO Mode only. 7. sysHSI Source Synchronous Receive Mode is not available for channel 3A. 67 Lattice Semiconductor ispGDX2 Family Data Sheet Part Number
