Applications Engineering
INTRODUCTION
The purpose of this application note is to provide the
design engineer with information and techniques to modify
existing MC13110/13111 Universal Cordless Telephone
Subsystem
IC
designs
MC13110A,B/13111A,B. The MC13110A,B/13111A,B is a pin
compatible, improved 80% BiCMOS version of the
MC13110/13111, with additional functionality and superior
performance. Please refer to the MC13110A/D data sheet for
additional information about the MC13110A,B/13111A,B.

FIRST LOCAL OSCILLATOR
Figure 1 shows a typical varicap capacitance curve for
both the MC13110/111 and MC13110A,B/13111A,B. As can
be seen from these curves, the varicap of the
MC13110A,B/13111A,B is about 1.4 pF higher than that of
the MC13110/13111. As a result, either the external
capacitance (preferred) or inductance of the local oscillator
should be reduced.
Both the MC13110/13111 and MC13110A,B/13111A,B
incorporate internal, user selected capacitors that can be
used to extend the adjustable first local oscillator frequency
range. As shown in Table 1, there is a negligible difference
between capacitor select numbers 0–5. For applications
where capacitor select numbers 6 and 7 are being used on
the MC13110/13111, it is suggested that these be
re–mapped to MC13110A,B/13111A,B capacitor select
numbers 4 and 8, respectively.
