GM6535
60 MHz Universal Programmable
Dual PLL Frequency synthesizer
GENERAL DESCRIPTIONS
The GM6535 is a dual phase – locked loop
(PLL) frequency synthesizer especially designed for
CT-1 cordless phone applications worldwide. This
frequency synthesizer is also for any products with
frequency operation at 60 MHz or below.
The device features fully programmable
receive, transmit, reference, and auxiliary reference
counters accessed through an MCU serial interface,
this feature allows this device to operate in any CT-
1 cordless phone application.
The device consists of two independent phase
detectors for transmit and receive loops. A common
reference oscillator, driving two independent
reference frequency counters, provides independent
reference frequencies for transmit and receive loops.
The auxiliary reference counter allows the
user to select an additional reference frequency for
receive and transmit loops if required.
