ARCHIVE INFORMATION
The MC12053A is a super low power /64/65, /128/129 dual modulus prescaler. Motorola's advanced Bipolar MOSAICTM V technology is utilized to achieve low power dissipation of 4.3 mW at a minimum supply voltage of 2.7 V. The Divide Ratio Control input, SW, permits selection of divide ratio as desired. A HIGH on SW selects /64/65; an OPEN on SW selects /128/129. The Modulus Control input, MC, selects the proper divide number after SW has been biased to select the desired divide ratio. Stand-by mode is featured to reduce current drain to 50 A typical at 2.7 V when the stand-by pin, SB, is switched LOW, disabling the prescaler. On-chip output termination provides 500 A (typical) output current, which is sufficient to drive a CMOS synthesizer input high impedance load (8.0 pF typical). * 1.1 GHz Toggle Frequency
