EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508

 

 

The Stratix II GX family of devices is Altera’s third generation of FPGAs to combine high-speed serial transceivers with a scalable,high-performance logic array. EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508.Stratix II GX devices include 4 to 20 high-speed transceiver channels, each incorporating clock and data recovery unit (CRU) technology and embedded SERDES capability at data rates of up to 6.375 gigabits per second (Gbps). The transceivers are grouped into four-channel transceiver blocks and are designed for low power consumption and small die size. EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508

 

technology is built upon the Stratix II architecture and offers a 1.2-V logic array with unmatched performance, flexibility, and time-to-market capabilities. This scalable, high-performance architecture makes Stratix II GX devices ideal for high-speed backplane interface, chip-to-chip, and communications protocol-bridging applications.EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508

All Stratix II GX devices support vertical migration within the same package. Vertical migration means that you can migrate to devices whose dedicated pins, configuration pins, and power pins are the same for a given package across device densities. For I/O pin migration across densities, you must cross-reference the available I/O pins using the device pin-outs for all planned densities of a given package type to identify which I/O pins are migratable. Table 1–3 lists the Stratix II GX device package sizes.EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508

 

Stratix? II GX devices incorporate dedicated embedded circuitry on the right side of the device, which contains up to 20 high-speed 6.375-Gbps serial transceiver channels. Each Stratix II GX transceiver block contains four full-duplex channels and supporting logic to transmit and receive high-speed serial data streams. The transceivers deliver bidirectional point-to-point data transmissions, with up to 51 Gbps (6.375 Gbps per channel) of full-duplex data transmission per transceiver block. Figure 2–1 shows the function blocks that make up a transceiver channel

within the Stratix II GX device.EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508

 

The Stratix II GX receiver input buffer supports the 1.2-V and 1.5-V PCML I/O standard at rates up to 6.375 Gbps. The common mode voltage of the receiver input buffer is programmable between 0.85 V and 1.2 V.You must select the 0.85 V common mode voltage for AC- and DC-coupled PCML links and the 1.2 V common mode voltage for DC-coupled LVDS links.

Other Transceiver Features Other important features of the Stratix II GX transceivers are the power down and reset capabilities, external voltage reference and bias circuitry,

and hot swapping.EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508

 

The Stratix II GX device uses the calibration block to calibrate the on-chip termination for the PLLs and their associated output buffers and the terminating resistors on the transceivers. The calibration block counters the effects of process, voltage, and temperature (PVT). The calibration

block references a derived voltage across an external reference resistor to calibrate the on-chip termination resistors on the Stratix II GX device. The calibration block can be powered down. However, powering down the calibration block during operations may yield transmit and receive data errors.EP2SGX130GF1508C5N Altera IC STRATIX II GX 130K FBGA1508
