the mc12036 is a 1.1ghz 64/65, 128/129 dual modulus prescaler used in phaselocked loop (pll) applications. standby mode is featured to reduce current drain to 0.5ma typical when the standby pin (sb) is switched low, disabling the prescaler. onchip output termination provides sufficient output current to drive a 12pf (typical) high impedance load. the mc12036a can be used with cmos synthesizers requiring positive edges to trigger internal counters such as motorola's mc145xxx series in a pll to provide tuning signals up to 1.1ghz in programmable frequency steps. the mc12036b can be used with cmos synthesizers requiring negative edges to trigger internal counters. a divide ratio control (sw) permits selection of a 64/65 or 128/129 divide ratio as desired. the modulus control (mc) selects the proper divide number after sw has been biased to select the desired divide ratio. ? 1.1ghz toggle frequency ? low power 4.0ma typical ? standby mode ? onchip output termination ? supply voltage 4.5v to 5.5v ? operating temperature range of 40 c to +85 c ? short setup time (t set ) 16ns maximum @ 1.1ghz ? modulus control input level is compatible with standard cmos and ttl pinout: 8lead plastic (top view) 8 1 in in 7 2 sb v cc 6 3 mc sw 5 4 gnd out design criteria value unit internal gate count * 67 ea internal gate propagation delay 200 ps internal gate power dissipation 0.75 mw speed power product 0.15 pj *equivalent to a twoinput nand gate.
