www.DataSheet4U.com ML145162 60 MHz and 85 MHz Universal Programmable Dual PLL Frequency Synthesizers CMOS Legacy Device: Motorola MC145162 The ML145162 is a dual phase–locked loop (PLL) frequency synthesizer especially designed for CT–1 cordless phone applications worldwide. This frequency synthesizer is also for any product with a frequency operation at 60MHz or below. The device features fully programmable receive, transmit, reference, and auxiliary reference counters accessed through an MCU serial interface. This feature allows this device to operate in any CT–1 cordless phone application. The device consists of two independent phase detectors for transmit and receive loops. A common reference oscillator, driving two independent reference frequency counters, provides independent reference frequencies for transmit and receive loops. The auxiliary reference counter allows the user to select an additional reference frequency for receive and transmit loops if required. Operating Voltage Range: 2.5 to 5.5 V Operating Temperature Range: TA = – 40 to +75°C Operating Power Consumption: 3.0 mA @ 2.5 V Maximum Operating Frequency: 60 MHz @ 200 mV p–p, VDD = 2.5 V Three or Four Pins Used for Serial MCU Interface Built–In MCU Clock Output with Frequency of Reference Oscillator ÷3/÷4 Power Saving Mode Controlled by MCU Lock Detect Signal On–Chip Reference Oscillator Supports External Crystals to 16.0 MHz Reference Frequency Counter Division Range: 16 to 409...
