49 | /* |
50 | * Juli does not use the standard ICE1724 clock scheme. Juli's ice1724 chip is | |
51 | * supplied by external clock provided by Xilinx array and MK73-1 PLL frequency | |
52 | * multiplier. Actual frequency is set by ice1724 GPIOs hooked to the Xilinx. | |
53 | * | |
54 | * The clock circuitry is supplied by the two ice1724 crystals. This | |
55 | * arrangement allows to generate independent clock signal for AK4114's input | |
56 | * rate detection circuit. As a result, Juli, unlike most other | |
57 | * ice1724+ak4114-based cards, detects spdif input rate correctly. | |
58 | * This fact is applied in the driver, allowing to modify PCM stream rate | |
59 | * parameter according to the actual input rate. | |
60 | * | |
61 | * Juli uses the remaining three stereo-channels of its DAC to optionally | |
62 | * monitor analog input, digital input, and digital output. The corresponding | |
63 | * I2S signals are routed by Xilinx, controlled by GPIOs. | |
64 | * | |
65 | * The master mute is implemented using output muting transistors (GPIO) in | |
66 | * combination with smuting the DAC. | |
67 | * | |
68 | * The card itself has no HW master volume control, implemented using the | |
69 | * vmaster control. | |
70 | * | |
71 | * TODO: | |
72 | * researching and fixing the input monitors | |
