SAA1059

125 MHz AMPLlFIER AND DIVIDER-BY -32/33 The silieon monolithic integrated circuit SAA 1059 is designed as a programmable-ratio divide-by-32/33 prescaler. It is intended for use in digital radio tuning systems and frequency counters in radio applications wit h an input frequency range from 0,5 to 125 MHz. The high-frequency inputs are differential inputs of a preamplifier for handling a.m. as well as f.m. oscillator signals. One output set provides complementary ECL levels by emitter folIowers and a second output buffer set is intended to drive MOS circuits by open collectors. * QUICK REFERENCE DATA Supply voltage Input frequency range Input voltage range f = 0,5 to 30 MHz f=30to125MHz VCC2 Total power dissipation up to Tamb = 60 oC PACKAGE OUTLlNE 16-lead Dl L; plastic (SOT-38). fViPi(tromts) Vi(rms) VB 154 ±tmyVpa7.1x60. 0%01,mV550tWottoo 112050 mMVHz [January 19BO " "III/ IIIJ....I001aEClL IIor aoc L L or aoc L_ CM33 ~ H ET ~ H .; e N 'ulMu5.~i'~... 2J~-1~ ~ '" E M N 125 MHz amplifier and divider-by-32/33 SAA1059 no' n .1 .2.3 .16 .17 .18 .31 .32 .33 IN H ~---~---~ -+J ---r---j , -------~--~ -----t----- i ~_._~ 7Z80062.A '5 SEINT QaEECCLL orCQaMoOc3C3 HL H LL n-l n .1 H ~.
