    Audio DSP PCI Card: Chip Set

    Drawing



    Chips

    NOTE (for all readers)

    • There are no "hard-coded" chip-set decisions yet... we can still discuss about all chips.


    FPGA: XC3S400-5 PQ208

    DAC: AD1955
    • Manufacturer: Analog Devices
    • Distributor: DigiKey
    • Reasons: DSD/SACD support and probably best THDN performance. 192 kHz sample rate is supported.
    • Discussed with with: Sam (shimonkha@y...)
    ADC: 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: 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: 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: 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: 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: THS4131
    • Manufacturer: Texas Instruments
    • Distributor: DigiKey
    • Reasons: Fully balanced construction, very high GBP, great performances, simplest possible solution.
    • Decided in discussion with: Sam (shimonkha@y...)
    PLL: TLC2932
    • Manufacturer: Texas Instruments
    • Distributor: DigiKey
    • Reasons: There are no choice for wide locking range PLL.
    • Discussed with: Joe (jgrisso@d...)
    (TC)VCXO: ?
    • Manufacturer: ?
    • Distributor: ?
    • Reasons: ?
    • Discussed with: not discussed yet
    SDRAM: ?
    • Manufacturer: ?
    • Distributor: ?
    • Reasons: ?
    • Discussed with: not discussed yet
    SRAM: CY7C1041CV33-12ZC
    • Manufacturer: Cypress Semiconductor Corp.
    • Distributor: DigiKey
    • Reasons: High speed, 256kx16bits density, two chips only for 32bit bus.
    • Discussed with: Aaron (aaronwkm@o...)
    Flash: ?
    • Manufacturer: ?
    • Distributor: ?
    • Reasons: ?
    • Discussed with: not discussed yet
    USB: 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: 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@o...), Joe (jgrisso@d...)
