Chips

NOTE (for all readers) - There are no "hard-coded" chip-set decisions yet... we can still http://www.opencores.org/forums.cgi/cores/post (discuss) about all chips. FPGA: http://www.xilinx.com/xlnx/xweb/xil_publications_display.jsp?category=/Data+Sheets/FPGA+Device+Families/Spartan-3&iLanguageID=1 (XC3S400-5 PQ208) - Manufacturer: Xilinx - Distributor: Huhorizons - Reasons: Largest available Xilinx FPGA chip already supported in http://www.xilinx.com/xlnx/xebiz/designResources/ip_product_details.jsp?iLanguageID=1&sSecondaryNavPick=Design+Tools&key=DS-ISE-WEBPACK&BV_UseBVCookie=yes&sGlobalNavPick=PRODUCTS&BV_SessionID=@@@@0357914911.1086152484@@@@&BV_EngineID=cccdadcliekdhjicflgcefldfhndfmo.0 (WebPACK™ 6.2i) - Discussed with: Mikhail (mikem@opencores.org), Aaron (aaronwkm@opencores.org) . DAC: http://www.analog.com/Analog_Root/productPage/productHome/0,2121,AD1955,00.html (AD1955) - Manufacturer: Analog Devices - Distributor: DigiKey - Reasons: DSD/SACD support and probably best THD+N performance. 192 kHz sample rate is supported. - Discussed with with: Sam (shimonkha@yahoo.com) ADC: http://www.cirrus.com/en/products/pro/detail/P1024.html (CS5381) - Manufacturer: Cirrus Logic - Distributor: Memec - Reasons: There are no choice, if we need best ADC with 3.3V digital I/O posibility, needed by Spartan 3 FPGA. 192 kHz sample rate is supported. - Discussed with: not discussed yet DIR: http://www.cirrus.com/en/products/pro/detail/P1005.html (CS8416) - Manufacturer: Cirrus Logic - Distributor: Memec - Reasons: 192kHz maximum sampling rate is supported. Stable reference point for (future) VHDL AES3-S/PDIF receiver implementation possibility (with on-board dedicated multi stage PLL system). - Discussed with: not discussed yet DIT: http://www.cirrus.com/en/products/pro/detail/P1009.html (CS8406) - Manufacturer: Cirrus Logic - Distributor: Memec - Reasons: 192kHz maximum sampling rate is supported. Stable reference point for (future) VHDL AES3-S/PDIF transmitter implementation possibility. - Discussed with: not discussed yet ASRC: http://www.analog.com/Analog_Root/productPage/productHome/0,2121,AD1896,00.html (AD1896) - Manufacturer: Analog Devices - Distributor: Digikey - Reasons: Stable reference point for (future) VHDL ASRC implementation possibility. 192 kHz sample rate is supported. - Discussed with: not discussed yet AES3 Transformer: http://www.scientificonversion.com/catalog.html (SC979-03) - Manufacturer: Scientific Conversion, Inc. - Distributor: Scientific Conversion, Inc. - Reasons: Scientific Conversion is one of few _real_ AES3 trensformer manufacturers, and they produce best available components. - Discussed with: not discussed yet OPAMP: http://focus.ti.com/docs/prod/folders/print/ths4131.html (THS4131) - Manufacturer: Texas Instruments - Distributor: DigiKey - Reasons: Fully balanced construction, very high GBP, great performances, simplest possible solution. - Decided in discussion with: Sam (shimonkha@yahoo.com) PLL: http://focus.ti.com/docs/prod/folders/print/tlc2932.html (TLC2932) - Manufacturer: Texas Instruments - Distributor: DigiKey - Reasons: There are no choice for wide locking range PLL. - Discussed with: Joe (jgrisso@det3.net) (TC)VCXO: ? - Manufacturer: ? - Distributor: ? - Reasons: ? - Discussed with: not discussed yet SDRAM: ? - Manufacturer: ? - Distributor: ? - Reasons: ? - Discussed with: not discussed yet SRAM: http://www.cypress.com/products/datasheet.cfm?partnum=CY7C1041CV33 (CY7C1041CV33-12ZC) - Manufacturer: Cypress Semiconductor Corp. - Distributor: DigiKey - Reasons: High speed, 256kx16bits density, two chips only for 32bit bus. - Discussed with: Aaron (aaronwkm@opencores.org) Flash: ? - Manufacturer: ? - Distributor: ? - Reasons: ? - Discussed with: not discussed yet USB: http://www.ftdichip.com/DS245B.htm (FT245BM) - Manufacturer: FTDI Chip - Distributor: ? - Reasons: Royalty free drivers for most existing Operating Systems are available, and it is already supported in Linux® kernel. Third and probably cheapest way for card (FPGA) configuration. - Discussed with: not discussed yet CPLD: http://www.xilinx.com/xlnx/xweb/xil_publications_display.jsp?sGlobalNavPick=&sSecondaryNavPick=&category=-18744&iLanguageID=1 (XC9572XL) - Manufacturer: Xilinx - Distributor: DigiKey - Reasons: This will be an alternative way for FPGA configuration, support for USB chip. - Discussed with: not discussed yet FireWire PHY: None, sorry! - Manufacturer: - - Distributor: - - Reasons: We decide to not implement FireWire at this card. If any other interested to start another free hardware project for FireWire PCI card, we will help it. - Discussed with: Mikhail (mikem@opencores.org), Joe (jgrisso@det3.net) .
