The MC145162 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 product with a frequency operation at
60 MHz or below.
The MC145162–1 is a high frequency derivative of the MC145162, for
products with operating frequencies of 85 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.

power–down mode for current saving. (Other power down
modes are also provided through the control register per
Table 2 and Figure 8.) At the falling edge of the ENB signal,
the data is stored in the registers.
There are two interfacing schemes for the universal chan-
nel mode: the three–pin and the four–pin interfacing
schemes. The three–pin interfacing scheme is suited for use
with the MCU SPI (serial peripheral interface) (Figure 10),
while the four–pin interfacing scheme is commonly used for
general I/O port connection (Figure 11).
MCU PROGRAMMING SCHEME
The MCU programming scheme is defined in two formats
controlled by the ENB input. If the enable signal is high during
the serial data transfer, control register/reference frequency
programming is selected. If the ENB is low, programming of
the transmit and receive counters is selected. During pro-
gramming of the transmit and receive counters, both AD
and D pins can input the data to the transmit and receive
in
in
counters. Both counters’ data is clocked into the PLL internal
shift register at the leading edge of the CLK signal. It is not
necessary to reprogram the reference frequency counter/
control register when using the enable signal to program the
transmit/receive channels.
For the three–pin interfacing scheme, the auxiliary data
select bit is set to 0. All 32 bits of data, which define both the
16–bit transmit counter and the 16–bit receive counter, latch
into the PLL internal register through the data in pins at the
leading edge of CLK. See Figures 12 and 13.
In programming the control register/reference frequency
scheme, the most significant bit (MSB) of the programming
word identifies whether the input data is the control word or
the reference frequency data word. If the MSB is 1, the input
data is the control word (Figure 8). Also see Figure 8 and
Table 1 for control register and bit function. If the MSB is 0, the
input data is the reference frequency (Figure 9).
The reference frequency data word is a 32–bit word con-
taining the 12–bit reference frequency data, the 14–bit auxil-
iary reference frequency counter information, the reference
frequency selection plus, the auxiliary reference frequency
counter enable bit (Figure 9).
For the four–pin interfacing scheme, the auxiliary data
select bit is set to 1. In this scheme, the 16–bit transmit count-
er’s data enters into the AD pin at the same time as the
in
16–bit receive counter’s data enters into the D pin. This si-
in
multaneous entry of the transmit and receive counters
causes the programming period of the four–pin scheme to be
half that of the three–pin scheme (see Figures 14 and 15).
While programming Tx/Rx Channel Counter, the ENB pin
must be pulsed to provide falling edge to latch the shifted data
after the rising edge of the last clock. Maximum data transfer
rate is 500 kbps.
NOTE
If the AUX REF ENB bit is high, the 14–bit auxiliary refer-
ence frequency counter provides an additional phase refer-
ence frequency output for the loops. If AUX REF ENB bit is
low, the auxiliary reference frequency counter is forced into
10 ms should be allowed for initial start–up time
for the oscillator to allow all registers to clear and
enable programming of new register values.

specific reference frequency for a particular channel by using
two reference frequency counters (e.g., for an application in
France, the base set transmit channel common fixed refer-
ence frequency is 6.25 kHz or 12.5 kHz). (See Table 3 and
Figure 6 for reference frequencies for various countries.)
However, transmit channels 6, 8, and 14 can be set to
25 kHz, and channel 8 reference frequency can be set to
50 kHz. But this reference frequency may not be applied to
the receiving side; therefore, the receiving side reference fre-
quency must be generated by another reference frequency
counter. The higher the reference frequency, the better the
phase noise performance and faster the lock time, but the
PLL consumes more current if both reference frequency
counters are in operation.

Table 4 and Figure 16 describe the functions of the auxiliary

In general, the 12–bit reference frequency counter plus the
