Close - starting to the right of the circuit board

Power from PSU comes here

Fairchild MOSFET's















Linear Technology Regulators














An old USB receiver from TI - TAS1020B














From TI "This product is not recommended for new designs"
Why not use 24/192 Cypress USB receiver instead of the old TAS1020B?

Xilinx Spartan FPGA/DSP, Two gold crystal clocks above the Spartan.















Under Spartan there are three chips.














Left - AD1895:  192 kHZ Asynchronous Sample Rate Converter
Middle - Xilinx Flash for the Spartan FPGA chip
Right - AKM 4113 24/192 S/PDIF receiver

Going to the left of the circuit board
At the top - One AD1853 delta sigma 24/192 dac chip.














Under the dac chip there are two Lundahl LL1588 transformers
