1.1 GHz Low Power
Dual Modulus Prescaler
The MC12058 is a low power ÷126/128, ÷254/256 dual modulus prescaler. Motorola’s advanced Bipolar MOSAIC™ V technology is utilized to achieve low power dissipation of 3.0 mW at a minimum supply voltage of 2.7 V. The MC12058 can be operated down to a minimum supply voltage of 2.7 V required for battery operated portable systems.
On- chip output termination provides 250 µA (typical) output current to drive a 8.0 pF (typical) high impedance load. The Divide Ratio Control input, SW, permits selection of divide ratio as desired. A HIGH on SW selects ÷126/128; an OPEN on SW selects ÷254/256. The Modulus Control input, MC,...
