Bonjour à tous;
je voudrais savoir si cette série de FPGA utilise comme connecteur RS 232 ou bien LVDS d'apres ce que j'ai lu et si j'ai bien compris il utilise LVDS pour CONNECTER fpga au PC , c'est bien ça?
voilà qlq ligne de la datasheet
Introduction The Cyclone® field programmable gate array family is based on a 1.5-V,
0.13-μm, all-layer copper SRAM process, with densities up to
20,060 logic elements (LEs) and up to 288 Kbits of RAM. With features like
phase-locked loops (PLLs) for clocking and a dedicated double data rate
(DDR) interface to meet DDR SDRAM and fast cycle RAM (FCRAM)
memory requirements, Cyclone devices are a cost-effective solution for
data-path applications. Cyclone devices support various I/O standards,
including LVDS at data rates up to 640 megabits per second (Mbps), and
66- and 33-MHz, 64- and 32-bit peripheral component interconnect (PCI),
for interfacing with and supporting ASSP and ASIC devices. Altera also
offers new low-cost serial configuration devices to configure Cyclone
devices.
Features The Cyclone device family offers the following features:
■ 2,910 to 20,060 LEs, see Table 1–1
■ Up to 294,912 RAM bits (36,864 bytes)
■ Supports configuration through low-cost serial configuration device
■ Support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards
■ Support for 66- and 33-MHz, 64- and 32-bit PCI standard
■ High-speed (640 Mbps) LVDS I/O support
■ Low-speed (311 Mbps) LVDS I/O support
■ 311-Mbps RSDS I/O support
■ Up to two PLLs per device provide clock multiplication and phase
shifting
■ Up to eight global clock lines with six clock resources available per
logic array block (LAB) row
■ Support for external memory, including DDR SDRAM (133 MHz),
FCRAM, and single data rate (SDR) SDRAM
■ Support for multiple intellectual property (IP) cores, including
Altera® MegaCore® functions and Altera Megafunctions Partners
Program (AMPPSM) megafunctions.
