Description

section.

MC145191 2 MOTOROLA ELECTRICAL CHARACTERISTICS (VDD = VCC = 4.5 to 5.5 V, Voltages Referenced to GND, TA = 40 to + 85°C, unless otherwise stated; MC145190: VPD = 8.0 to 9.5 V; MC145191: VPD = 4.5 to 5.5 V with VDD ≤ VPD.) Symbol VIL VIH Vhys VOL VOH IOL IOH IO

Features

  • a single.
  • ended current source/sink phase detector output and a double.
  • ended phase detector output. Both phase detectors have linear transfer functions (no dead zones). The maximum current of the single.
  • ended phase detector output is determined by an external resistor tied from the Rx pin to ground. This current can be varied via the serial port. The MC145190 features logic.
  • level converters and high.
  • voltage phase/ frequency detectors; the detector supply ma.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145190/D 1.1 GHz PLL Frequency Synthesizers MC145190 MC145191 Include On–Board 64/65 Prescalers The MC145190 and MC145191 are single–package synthesizers with serial interfaces capable of direct usage up to 1.1 GHz. A special architecture makes these PLLs very easy to program because a byte–oriented format is utilized. Due to the patented BitGrabber™ registers, no address/steering bits are required for random access of the three registers. Thus, tuning can be accomplished via a 3–byte serial transfer to the 24–bit A register. The interface is both SPI and MICROWIRE™ compatible. Each device features a single–ended current source/sink phase detector output and a double–ended phase detector output.
