Motorola’s advanced Bipolar MOSAIC™ Vtechnology is utilized to achieve low power dissipation of 2.7 mW at aminimum supply voltage of 2.7 V.The MC12052A can be used with CMOS synthesizers requiring positiveedges to trigger internal counters such as Motorola’s MC145XXX series in aPLL to provide tuning signals up to 1.1 GHz in programmable frequencysteps.A Divide Ratio Control (SW) permits selection of a 64/65 or 128/129 divideratio as desired.The Modulus Control (MC) selects the proper divide number after SW hasbeen biased to select the desired divide ratio.•1.1 GHz Toggle Frequency•The MC12052 is Pin and Functionally Compatible with the MC12022•Low Power 1.0 mA Typical•2.0 mA Maximum, –40 to 85°C, V = 2.7 to 5.5 Vdc•CCShort Setup Time (t•set) 16 ns Maximum @ 1.1 GHzModulus Control Input Level is Compatible with Standard CMOS andTTL•Maximum Input Voltage Should Be Limited to 6.5 VdcMOSAIC V is a trademark of MotorolaFUNCTIONAL TABLESWMCDivide RatioHH64HL65LH128LL129NOTES:1.SW: H = VCC, L = Open.
