49 * Juli does not use the standard ICE1724 clock scheme. Juli's ice1724 chip is
50 * supplied by external clock provided by Xilinx array and MK73-1 PLL frequency
51 * multiplier. Actual frequency is set by ice1724 GPIOs hooked to the Xilinx.
53 * The clock circuitry is supplied by the two ice1724 crystals. This
54 * arrangement allows to generate independent clock signal for AK4114's input
55 * rate detection circuit. As a result, Juli, unlike most other
56 * ice1724+ak4114-based cards, detects spdif input rate correctly.
57 * This fact is applied in the driver, allowing to modify PCM stream rate
58 * parameter according to the actual input rate.
60 * Juli uses the remaining three stereo-channels of its DAC to optionally
61 * monitor analog input, digital input, and digital output. The corresponding
62 * I2S signals are routed by Xilinx, controlled by GPIOs.
64 * The master mute is implemented using output muting transistors (GPIO) in
65 * combination with smuting the DAC.
67 * The card itself has no HW master volume control, implemented using the
68 * vmaster control.
