1 / 11 page www.lansdale.com Page 1 of 11 Issue A ML12202 MECL PLL Components Serial Input PLL Frequency Synthesizer Legacy Device: Motorola MC12202 The ML12202 is a 1.1 GHz Bipolar monolithic serial input phase locked loop (PLL) synthesizer with pulse–swallow func- tion. It is designed to provide the high frequency local oscillator signal of an RF transceiver in handheld communication applica- tions. The technology is utilized allows for low power operation at a minimum supply voltage of 2.7 V. The device is designed for operation over 2.7 to 5.5 V supply range for input frequencies up to 1.1 GHz with a typical current drain of 6.5 mA. The low power consumption makes the ML12202 ideal for handheld bat- tery operated applications such as cellular or cordless tele- phones, wireless LAN or personal communication services. A dual modulus prescaler is integrated to provide either a 64/65 or 128/129 divide ratio. • Low Power Supply Current of 5.8 mA Typical for ICC and 0.7 mA Typical for IP • Supply Voltage of 2.7 to 5.5 V • Dual Modulus Prescaler With Selectable Divide Ratios of 64/65 or128/129 • On–Chip Reference Oscillator/Buffer • Programmable Reference Divider Consisting of a Binary 14–Bit Programmable Reference Counter • Programmable Divider Consisting of a Binary 7–Bit Swallow Counter and an 11–Bit Programmable Counter • Phase/Frequency Detector With Phase Conversion Function • Balanced Charge Pump Outputs • Dual Internal Charge Pumps for Bypassing the First Stage of the Loop Filter to Decrease Lock Time • Outputs for External Charge Pump • Operating Temperature Range of TA = –40 to 85°C NOTE: Also available is the ML12210, a 2.5 GHz version of this function. Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE. |
