MC145166 Datasheet Dual Plls For 46/49 Mhz Cordless Telephones

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145166/D MC145166 Dual PLLs for 46/49 MHz Cordless Telephones MC145167 CMOS These devices are dual phase–locked loop (PLL) frequency synthesizers in– tended for use primarily in 46/49 MHz cordless phones with up to 10 channels. These parts contain two mask–programmable counter ROMs for receive and transmit loops with two independent phase detect circuits. A common reference oscillator and reference divider are shared by the receive and transmit circuits. Frequency selection is accomplished via a 4–bit parallel input for the MC145166. The MC145167 utilizes a serial interface.

Key Features

  • include a lock detect circuit for the transmit loop, illegal code default, and a 5 kHz tone output.
  • Synthesizes Up to Ten Channel Pairs Maximum Operating Frequency: 60 MHz @ Vin = 200 mV p.
  • p Operating Temperature Range:.
  • 40 to + 75°C Operating Voltage Range: 2.5 to 5.5 V On.
  • Chip Oscillator Circuit Supports External Crystal Lock Detect Signal Operating Power Consumption: 3.0 mA @ 3.0.
