Product Q & A
Review
Note： This is a assembeld board
Works voltage: AC9-12V
PCB Size:89mmx75mm
Installation hole distance 78.82x64.86mm
The maximum height is about 22mm
this board can output any one of the following: 8.4672M / 11.2896M / 16.9344M / 33.8688M
Can solve almost all high-demand CD or LD machine replacement solutions
When the install to machine, first remote the original clock circuit and connect the corresponding frequency to the clock input of the original DSP will be ok.
The master clock of an ordinary CD or LD is composed of a oscillating circuit built in a DSP or a DAC chip plus a quartz crystal. This kind of clock circuit has poor working stability and is susceptible to power supply noise/temperature variations and the like. The timing of the DAC conversion is derived from this master clock. Therefore, a precise clock system is needed to replace the original machine clock to ensure jitter is minimal.
We have developed this clock board that uses a separate power supply design for crystals susceptible to power disturbances, and does not interact with other circuits in order to be able to output high-stabilization frequencies for CD or LD use.
This board uses a divider circuit to reduce the jitter to 1/N. The jitter can be reduced several times without having to purchase an extremely expensive low jitter clock crystal.
The main filter capacitor can be used axially or vertically, and the vertical capacitor can also be mounted in the same way as the axial capacitor, which facilitates the installation of the short chassis.
