STMicroelectronics STV5730A
The STV5730A IC is intended to be used in VCR, Satellite receiver and PAY-TV systems for CVBS or R/G/B text/graphics insertion. This pin may be connected to the YIN input for minimum cost applications. The STV5730A extracts the sync from this signal when the C7 control bit is set.| Part No. | STV5730A |

Analog Output This pin outputs the luma to allow the user to notch filter it. VIDEO IN Analog Input This is the CVBS input. An external capacitor is needed for clamp operation. RES Analog Pin it must be tied to an external resistor to control the PLL f0 frequency. FTR Analog Pin it must be tied to the line PLL loop filter. Supply Pin 5V analog supply pin. AVDD DVDD Supply Pin 5V digital supply pin. CSYNC Bidirectional This pin inputs the mixed mode composite sync when the C7 control bit is Pin cleared. It outputs the video in extracted sync when the C7 control bit is set. XTAL IN Digital Input This is the 4*fsc quartz input. The quartz may be started or stopped under control of dedicated serial interface messages. Alternatively, a 4fsc clock can be input directly. The stop message must not be used in this case. XTAL OUT Digital Output This is the 4*fsc quartz output.
