ML12210 - Serial Input PLL Frequency Synthesizer

Features

  • ing edges of the VCO (fp) signal and the reference (fr) input. Since these edges occur only once per cycle, the detector has a range of ±2π radians. The phase comparator outputs are standard CMOS rail.
  • to.
  • rail levels (VP to GND for φP and VCC to GND for φR), designed for up to 20MHz operation into a 15pF load. These phase comparator outputs can be used along with an external charge pump to enhance the PLL characteristics. The operation of the phase comparator is shown in Figures 3.

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.
