Freescale Semiconductor, Inc.Order this document by MC12058/D ARCHIVED BY FREESCALE SEMICONDUCTOR, INC. 2005 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, selects the proper divide number after SW has been biased to select the desired divide ratio. • 1.1 GHz Toggle Frequency • • • • MECL PLL COMPONENTS ÷126/128, ÷254/256 LOW POWER DUAL MODULUS PRESCALER SEMICONDUCTOR TECHNICAL DATA ARCHIVE INFORMATION ARCHIVED BY FREESCALE SEMICONDUCTOR, INC. 2005 Freescale Semiconductor, Inc...
