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.

* Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the limits in the Electrical Characteristics
tables or Pin Descriptions section.
This device contains protection circuitry to
guard against damage due to high static voltages or electric fields. However, precautions
must be taken to avoid application of any voltage
higher than maximum rated voltages to this
high–impedance circuit. For proper operation,
Vin and Vout should be constrained to the range
VSS ≤ (Vin or Vout) ≤ VDD.
Unused pins must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.

PIN DESCRIPTIONS
INPUT PINS
fin–T/fin–R
Transmit/Receive Counter Inputs (Pins 14, 9)
OSCin /OSCout
Reference Oscillator Input/Output (Pins 7, 8)
These pins form a reference oscillator when connected to
an external parallel–resonant crystal. Figure 6 shows the
relationship of different crystal frequencies and reference
frequencies for cordless phone applications in various countries. OSCin may also serve as input for an externally generated reference signal which is typically ac coupled.
fin–T and fin–R are inputs to the transmit and the receive
counters, respectively. These signals are typically driven from
the loop VCO and ac coupled. The minimum input signal level
is 200 mV p–p @ 60.0 MHz.
OUTPUT PINS
TxPDout/RxPDout
Transmit/Receive Phase Detector Outputs (Pins 15, 10)
MCUCLK
System Clock (Pin 5)
This output pin provides a signal of the crystal frequency
(OSC out) divided by 3 or 4 that is controlled by a bit in the
control register.
This signal can be a clock source for the MCU or other system clocks.
ADin, Din, CLK, ENB
Auxiliary Data In, Data In, Clock, Enable (Pins 2, 3, 1, 4)
These are three–state outputs of the transmit and receive
phase detectors for use as loop error signals (see Figure 7 for
phase detector output waveforms). Phase detector gain is
VDD/4 π volts per radian.
Frequency fV > fR or fV leading: output = negative pulse.
Frequency fV < fR or fV lagging: output = positive pulse.
Frequency fV = fR and phase coincidence: output = high–
impedance state.
NOTE: fR is the divided–down reference frequency at the
phase detector input and fV is the divided–down VCO
frequency at the phase detector input.
These four pins provide an MCU serial interface for programming the reference counter, the transmit–channel counter, and the receive–channel counter. They also provide
various controls of the PLL including the power saving mode
and the programming format.
LD
Lock Detect (Pin 16)
TxPS/fTx, RxPS/fRx
Transmit Power Save, Receive Power Save (Pins 13, 11)
The lock detect signal is associated with the transmit loop.
The output at a high level indicates an out–of–lock condition
(see Figure 7 for the LD output waveform).
For a normal application, these output pins provide the
status of the internal power saving mode operation. If the
transmit–channels counter circuitry is in power down mode,
TxPS/f Tx outputs a high state. If the receive–channels
counter circuitry is in power down mode, RxPS/fRx is set high.
These outputs can be applied for controlling the external power switch for the transmitter and the receiver to save MCU
control pins.
In the Tx/Rx channel counter test mode, the TxPS/fTx and
RxPS/f Rx pins output the divided value of the transmit
channel counter (fTx) and the receive channel counter (fRx),
respectively. This test mode operation is controlled by the
POWER SUPPLY
VDD
Positive Power Supply (Pin 12)
VDD is the most positive power supply potential ranging
from 2.5 to 5.5 V with respect to VSS.
VSS
Negative Power Supply (Pin 6)
VSS is the most negative supply potential and is usually
connected to ground.

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 programming of the transmit and receive counters, both ADin
and Din pins can input the data to the transmit and receive
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.
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 containing the 12–bit reference frequency data, the 14–bit auxiliary reference frequency counter information, the reference
frequency selection plus, the auxiliary reference frequency
counter enable bit (Figure 9).
If the AUX REF ENB bit is high, the 14–bit auxiliary reference frequency counter provides an additional phase reference frequency output for the loops. If AUX REF ENB bit is
low, the auxiliary reference frequency counter is forced into
MOTOROLA
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 channel 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).
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.
For the four–pin interfacing scheme, the auxiliary data
select bit is set to 1. In this scheme, the 16–bit transmit counter’s data enters into the ADin pin at the same time as the
16–bit receive counter’s data enters into the Din pin. This simultaneous 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
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.

Figure 16 shows the bit function of the reference frequency
programming word. The user can either select the “fixed”
reference frequency for all channels accordingly or provide a
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 reference 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 frequency 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.
In general, the 12–bit reference frequency counter plus the
4 and 25 module can offer all the reference frequencies

REFERENCE FREQUENCY SELECTION
AND PROGRAMMING
fR1
for global CT–1 transmit and receive channel requirements.
Users can select their own reference frequency by introducing the additional 14–bit auxiliary reference frequency
counter.
Again, the 14–bit auxiliary reference frequency counter can
be shut down by the auxiliary reference enable bit in the reference counter programming word by setting the bit to 0. At this
state, the fR2 is automatically connected to point C (the 25
block output), and fR1 can be connected to point A or B by setting the fR1–S1 and fR1–S2 bits in the reference counter program word. The 14–bit auxiliary reference frequency counter
data will be in “Don’t Care” state.
If the 14–bit auxiliary reference frequency counter is
enabled (auxiliary reference enable = 1), then fR2 is automatically connected to point D (14–bit counter output), and
fR1 can be selected to connect to point A, B, or C, depending
on the bit setting of fR1–S1 and fR1–S2.
Table 4 and Figure 16 describe the functions of the auxiliary
reference enable bit and the f R1 –S1 and f R1 –S2 bits
selection.

POWER SAVING OPERATION
This PLL has a programmable power–saving scheme. The
transmit and receive counters and the reference frequency
counter can be powered down individually by setting the
TxPD enable, RxPD enable, and Ref PD enable bits of the
control register. The functions of the power down control bits
are explained in Table 2 and the programming format is in
Figure 8.
The output pins TxPS/fTx and RxPS/fRx output the status of
the internal power saving setting. If the bit TxPD enable is set
“high” (transmit counter is set to power–down mode), then the
TxPS/fTx pin will also output a “high” state. This TxPS/fTx output can control an external power switch to switch off the
transmitter, as shown in Figure 17. This scheme can be
applied to the RxPS/fRx output to control the receiver power
saving operation as required.

Tx/Rx CHANNEL COUNTER TEST
In normal applications, the TxPS/fTx and the RxPS/fRx output pins indicate the power saving mode status. However, the
user can examine the Tx and Rx channel counter outputs by
setting the Test bit in the control register to 1. The final value
of the transmit–channel counter and the receive–channel
counter multiplex out to TxPS/fTx and RxPS/fRx respectively.
The user can verify the divided–down output waveform associated with the RF input level in the PLL circuitry implementation (Figure 18).
