When combined with an external low–pass filter and voltage–controlled oscillator, these devices can provide all the remaining functions for a PLL frequency synthesizer operating up to the device's frequency limit. For higher VCO frequency operation, a down mixer or a prescaler can be used between the VCO and the synthesizer IC. These frequency synthesizer chips can be found in the following and other applications: CATV TV Tuning AM/FM Radios Scanning Receivers Two–Way Radios Amateur Radio OSC ÷R CONTROL LOGIC φ ÷A ÷N ÷ P/P + 1 VCO OUTPUT FREQUENCY EXTERNAL COMPONENTS CONTENTS Page DEVICE DETAIL SHEETS ML145151 Parallel–Input, Single–Modulus ...........................................................................................2 ML145152 Parallel–Input, Dual–Modulus..............................................................................................5 ML145155 Serial–Input, Single–Modulus ..............................................................................................9 ML145156 Serial–Input, Dual–Modulus...............................................................................................13 ML145157 Serial–Input, Single–Modulus .................................................................................
