150 MHz PIXEL VIDEO CONTROLLER FOR MONITORS

STMicroelectronics 

TDA9210

Functioning with 5 V Power VCC

To simplify the application, it is possible to supply

the power VCC with 5 V (instead of 8 V nominal) at

the expense of output swing voltage.

Functioning without Blanking Pulse

If no blanking pulse is applied to the TDA9210, the

internal BPCP can be connected to the sample

Figure 3. Waveforms VOUT, BRT, CONT, OSD

and hold circuit (Register 8, bit 7 = 1 and BLK pin

grounded) so that the output DC level is still con-

trolled by I2C.

To ensure the device correct behavior in the worst

possible conditions, the Brightness Register must

be set to 0.
