4 pairs of synchronous control signals are converted into 4 single-ended signals, if the quantity of the chip 103 of single-ended transfer difference is 5,
4 single-ended signals are now respectively sent to 5 chips of single-ended transfer difference 103, the chip of each single-ended transfer difference
Input interface be at least 4, turn 4 single-ended signals that single-ended chip 102 sends to receive difference, now,
It is that 4 single-ended signals are converted into 4 pairs of synchronous conversion signals for a chip for single-ended transfer difference, by
Can be with concurrent working in the chip 103 of single-ended transfer difference, thus 5 chips of single-ended transfer difference 103 are most poor at last
4 single-ended signals exported in the chip 102 for turning single-ended are divided to be converted to 4 × 5 pairs of synchronous conversion signals.
Multiple output interfaces 104, each output interface 104 is electrically connected with the chip 103 of corresponding single-ended transfer difference,
For M to be exported to synchronous conversion signal.
The quantity of output interface 104 is equal with the quantity of the chip 103 of single-ended transfer difference, is M divided by N number of.
Each output interface is corresponding with the chip 103 of each single-ended transfer difference, and the chip 103 for receiving single-ended transfer difference is defeated
The synchronous conversion signal for going out, and further by multiple output interfaces 104 M is exported to synchronous conversion signal
Give reception board.If the quantity of the synchronous conversion signal of receiver board calorie requirement is less than M, receiving board can be according to certainly
Oneself demand carries out logic realization.
It should be noted that the chip 103 of single-ended transfer difference and the quantity of output interface 104 are with three in Fig. 1
As a example by illustrated, but not represent the quantity of the chip 103 of single-ended transfer difference be only three, its number
Amount can be to be modified according to actual needs.
The synchronizing signal Control card that the present invention is provided passes through N using the single-ended chip 102 of difference turn to synchronous control
Signal processed is converted to N number of single-ended signal, and N number of single-ended signal is separately input into the chip of multiple single-ended transfer differences
103, so as to N number of single-ended signal is converted into M to synchronous conversion signal, M/N is the chip 103 of single-ended transfer difference
Quantity, thus, N is expanded into M to synchronous control signal to synchronous conversion signal, realize to synchronizing signal
Expand, demand of the printing digital display circuit for color expansion can be met.
Embodiment two
The present embodiment provides a kind of synchronizing signal control method, and the executive agent of the present embodiment is the core of single-ended transfer difference
