" the MC12083 is a 2 prescaler for low power frequency division of a 1.1ghz high frequency input signal. onchip output termination provides output current to drive a 2pf (typical) high impedance load. if additional drive is required for the prescaler output, an external resistor can be added parallel from the out pin to gnd to increase the output power. care must be taken not to exceed the maximum allowable current through the output. standby mode is featured to reduce current drain to 250 m a typical when the standby pin sb is switched low disabling the prescaler. ? 1.1ghz toggle frequency ? supply voltage 2.7v to 5.5v ? low power 4.5ma typical at v cc = 2.7v ? operating temperature 40 to +85 c ? onchip termination 8 1 in in 7 2 sb v cc 6 3 nc nc 5 4 gnd out pinout: 8lead plastic (top view) a low on the standby pin 7 disables the device. maximum ratings symbol parameter value unit v cc power supply voltage, pin 2 0.5 to +7.0 vdc t a operating temperature range 40 to +85 c t stg storage temperature range 65 to +150 c i o maximum output current, pin 4 10.0 ma mecl pll components 2 prescaler with standby mode p suffix 8lead plastic package case 62605 d suffix 8lead plastic soic package case 75105
