MC145155FN2

The MC145155FN2 is designed as one kind of PLL frequency synthesizer that is typically used as lowpower, phaselocked loop frequency synthesizers. And this device can provides all the remaining functions for a PLL frequency synthesizer operating up to the device's frequency limit. So it can be used in (1)CATV ; (2)TV tuning; (3)AM/FM radios ; (4)scanning receivers; (5)twoway radios ; (6)amateur radio.

Features of the MC145155FN2 are:(1)Operating Temperature Range: -40 to 85 ; (2)Low Power Consumption Through Use of CMOS Technology; (3)3.0 to 9.0 V Supply Range; (4)On- or Off - chip Reference Oscillator Operation; (5)Lock Detect Signal; (6)/N Counter Output Available; (7)?Single Modulus/Parallel Programming; (8)8 User - selectable ?R Values: 8, 128, 256, 512, 1024, 2048, 2410, 8192; (9)/N Range = 3 to 16383; (10)linearized Digital Phase Detector Enhances Transfer Function Linearity; (11)Two Error Signal Options: Single - ended (Three - state) or Double - ended; (12)Chip Complexity: 8000 FETs or 2000 Equivalent Gates.

The phase detector outputs of this device can be combined externally for a looperror signal. A singleended output is also available for this purpose. If you want to know more information about it, please download the datasheet in www.seekic.com or www.chinaicmart.com .
