简  介: ML145159 Serial-Input PLL Frequency Synthesizer with Analog Phase Detector INTERFACES WITH DUAL–MODULUS PRESCALERS Legacy Device: Motorola MC145159-1 The ML145159 has a programmable 14–bit reference counter, as well as fully programmable divide–by–N/divide–by–A counters. The counters are programmed serially through a common data input and latched into the appropriate counter latch, according to the last data bit (control bit) entered. When combined with a loop filter and VCO, this device can provide all the remaining functions for a PLL frequency synthesizer operating up to the device's frequency limit. For higher VCO frequency operations, a down mixer or a dual–modulus prescaler can be used between the VCO and the PLL. Operating Temperature Range: TA – 40° to 85°C Low Power Consumption Through Use of CMOS Technology 3.0 to 9.0 V Supply Range On– or Off–Chip Reference Oscillator Operation Compatible with the Serial Peripheral Interface (SPI) on CMOS MCUs ÷ R Range = 3 to 16383 ÷ N Range = 16 to 1023, P A Range = 0 to 127 High–Gain Analog Phase Detector See Application Note AN969 Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.
