Poor quality clocks are widely spread into audio electronics. A few good upgrade solutions are available, with the drawback that only one frequency is usually generated. The audiokit clock is a versatile, high-performance module that offers the unique feature of having all usual frequencies used in digital audio, simply selectable via the on-board mini-switch.
Details:
high performance ECL clock generator
multiple frequencies available on a single board
low jitter output (only 10 pS rms)
differential clock output for advanced designs
high drive capability
serial resonance high-quality custom crystal
smd technology
LVTTL compatible outputs
| Frequency /DIP switch position* |
1 | 2 | 3 | 4 |
| 8,4672 Mhz | OFF | ON | OFF | OFF |
| 16,9344 Mhz | OFF | ON | ON | OFF |
| 33,8688 Mhz | OFF | ON | OFF | ON |
| 67,7376 Mhz | OFF | ON | ON | ON |
| 11,2896 Mhz | ON | OFF | OFF | OFF |
| 22,5792 Mhz | ON | OFF | ON | OFF |
| 45,1584 Mhz | ON | OFF | OFF | ON |
*Note: frequency changes are active after reset (power supply off-on)
The module needs 9Vdc/0,25A supply, so make sure that your player has this capability. Identify the quartz frequency looking on the markings on it, otherwise a good reference table can be found here. Remove the crystal and the capacitors connected on it, set the clock module accordingly and connect it to the input of the inverter in the original configuration**.
The schematic of the clock is shown on the left diagram. The signal is synthesised in high-quality PECL logic and sent to a ultrafast comparator to accomodate the logic levels used in your player.
