EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672

Overview The Stratix? GX family of devices is Altera’s second FPGA family to combine high-speed serial transceivers with a scalable, high-performance logic array. Stratix GX devices include 4 to 20 high-speed transceiver channels, each incorporating clock data recovery (CDR) technology and embedded SERDES capability at data rates of up to 3.1875 gigabits per second (Gbps). EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672

 

These transceivers are grouped by four-channel transceiver blocks, and are designed for low power consumption and small die size. The Stratix GX FPGA technology is built upon the Stratix architecture, and offers a 1.5-V logic array with unmatched performance,flexibility, and time-to-market capabilities. This scalable,high-performance architecture makes Stratix GX devices ideal for high-speed backplane interface, chip-to-chip, and communications protocol-bridging applications.EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672

The Stratix GX device family supports high-speed serial transceiver blocks with CDR circuitry as well as source-synchronous interfaces. EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672 The channels on the right side of the device use an embedded circuit dedicated for receiving and transmitting high-speed serial data streams to and from the system board. EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672. These channels are clustered in a four-channel serial transceiver building block and deliver high-speed bidirectional point-to-point data transmissions to provide up to 3.1875 Gbps of full-duplex data transmission per channel.  EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672

 

The channels on the left side of the device support source-synchronous data transfers at up to 1 Gbps using LVDS, LVPECL, 3.3-V PCML, or HyperTransport technology I/O standards. Figure 1–1 shows the Stratix GX I/O blocks.The differential source-synchronous serial interface and the high-speed serial interface are described in the Stratix GX Transceivers chapter of the Stratix GX Device Handbook EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672 FPGA Functional

 

Stratix GX devices contain a two-dimensional row- and column-based architecture to implement custom logic. A series of column and row interconnects of varying length and speed provide signal interconnects between logic array blocks (LABs), memory block structures, and DSP blocks. EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672.The logic array consists of LABs, with 10 logic elements (LEs) in each LAB. An LE is a small unit of logic providing efficient implementation of

user logic functions. LABs are grouped into rows and columns across the device. M512 RAM blocks are simple dual-port memory blocks with 512 bits plus parity (576 bits). These blocks provide dedicated simple dual-port or single-port memory up to 18-bits wide at up to 318 MHz. M512 blocks are grouped into columns across the device in between certain LABs.M4K RAM blocks are true dual-port memory blocks with 4K bits plus parity (4,608 bits). These blocks provide dedicated true dual-port, simple dual-port, or single-port memory up to 36-bits wide at up to 291 MHz.These blocks are grouped into columns across the device in between certain LABs.EP1SGX25CF672C6ES Altera IC STRATIX GX FPGA 25KLE FBGA672 .Transceiver Blocks Stratix? GX devices incorporate dedicated embedded circuitry on the right side of the device, which contains up to 20 high-speed 3.1875-Gbps serial transceiver channels. Each Stratix GX transceiver block contains four full-duplex channels and supporting logic to transmit and receive high-speed serial data streams. The transceiver block uses the channels to deliver bidirectional point-to-point data transmissions with up to 3.1875 Gbps of data transition per channel.
