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.
Other features include a lock detect circuit for the transmit loop, illegal code
default, and a 5 kHz tone output.

This device contains protection circuitry to
guard against damage due to high static voltages or electric fields. However, precautions
must be taken to avoid applications of any
voltage higher than maximum rated voltages
to this high–impedance circuit. For proper operation, Vin and V
out
should be constrained to
the range VSS≤ (Vin or V
out
) ≤ VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either V
SS
or VDD). Unused outputs must be left open.
