UPC1861

The UPC1861 is an LSI chip which incorporates a PLL circuit to generate clocks whose frequency is multipiable by fH(horizontal sync signal frequency)and it ideal for the processing of digital video signals.The UPC1861 adopts a pin small outline package (SOP) and thus saves mounting space on a PC board.

Features of the UPC1861 are:(1)VCO is incorporated(may be used up to 1820fH);(2)horizontal sync separator is incorporated;(3)low current consumption.

The absolute maximum ratings of the UPC1861 can be summarized as:(1):the parameter is supply voltage,the symbol is VCC,the rating is 7,the unit is V;(2):the parameter is supply voltage,the symbol is VDD,the rating is 7,the unit is V;(3):the parameter is composive video input signal voltage,the symbol is ei2,the rating is 3,the unit is Vp-p;(4):the parameter is input voltage,the symbol is ei,the rating is -0.5 to VDD+0.5,the unit is V;(5):the parameter is input seiect voltage,the symbol is V16,the rating is -0.5 to VDD+0.5,the unit is V;(6):the parameter is power dissipation of package,the symbol is PD,the rating is 275,the unit is mW;(7):the parameter is storage temperature,the symbol is Tstg,the rating is -40 to 125,the unit is ;(8):the parameter is operating temperature,the symbol is Topr,the rating is -10 to +75,the unit is .
