ML12210

ML12210 Serial Input PLL Frequency Synthesizer Legacy Device: Motorola MC12210 The ML12210 is a 2.5 GHz Bipolar monolithic serial input phase locked loop (PLL) synthesizer with pulse–swallow function. It is designed to provide the high frequency local oscillator signal of an RF transceiver in handheld communication applications. The technology used 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 2.5 GHz with a typical current drain of 9.5 mA. The low power consumption makes the ML12210 ideal for handheld battery operated applications such as cellular or cordless telephones, wireless LAN or personal communication services. A dual modulus prescaler is integrated to provide either a 32/33 or 64/65 divide ratio. 16 1 SO 16 = -5P PLASTIC PACKAGE CASE 751B (SO–16) Low Power Supply Current of 8.8 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 32/33 or 64/65 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 ...
