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