New Motorola Cordless Telephone Combo ICs Offer
Wider Tuning, Improved Sensitivity and Lower Power
Simplifies Implementation of the 25-Channel Standard
The MC13110A and MC13111A Universal Cordless Telephone Subsystem
ICs integrate nearly all the major functions required for a cordless telephone on a
single integrated circuit. These devices integrate a number of analog and discrete RF
functions to achieve significantly reduced component count, lower board space require-
ments, and fewer external adjustments, all with very low power dissipation.
All versions of the MC13110A and MC13111A cordless combo ICs integrate
a dual conversion FM receiver, compander, dual universal programmable PLL, and
low battery detect in a family of single ICs with a variety of functional and package
options. The MC13110A also integrates a frequency inversion voice scrambler/
descrambler to provide increased cordless phone privacy. On-chip digitally-pro-
grammable features integrate several tuning functions to eliminate manual tuning
during the customers’ manufacturing process.
These new A suffixed devices provide several improved specifications and
additional features that were not available in the older MC13110 and MC13111 ICs. The
newer family has improved the input sensitivity by 3.0 dB, lowered the drain current
from 12 mA to 10.5 mA maximum, and increased the gain of the reference oscillator.
Internal capacitor selections have increased from five to sixteen to simplify the
implementation of 25 channel applications.
