MOTOROLA RF/IF DEVICE DATA
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
A (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, selects the proper divide number after SW has been biased to select the
desired divide ratio.
1.1 GHz Toggle Frequency
Supply Voltage 2.7 to 5.5 V
Low Power 1.1 mA Typical at VCC = 3.0 V
Operating Temperature Range of –40 to 85°C

NOTES: 1. SW: H = VCC, L = Open. A logic L can also be applied by grounding this pin,
but this is not recommended due to increased power consumption.
2. MC: H = 2.0 V to VCC, L = GND to 0.8 V.
