LC72144M
PLL Frequency Synthesizer
Overview
The LC72144M is an electronic tuning PLL frequency
synthesizer for use in car and home products, and allows
high-performance multifunction tuners to be implemented
easily, since it includes an A/D converter, a high-speed
lockup circuit, and a crystal oscillator circuit that support
AM up-conversion.

Function
Crystal oscillator connection
(4.5, 7.2, 10.25, or 10.35 MHz)
FMIN is selected when DVS in the serial data input is set to 1.
The input frequency range is 10 to 160 MHz.
The signal is transmitted to the swallow counter.
The divisor can be set to a value in the range 272 to 65,535.
AMIN is selected when DVS in the serial data input is set to 0.
When SNS in the serial data input is set to 1:
• The input frequency range is 2 to 40 MHz.
• The signal is transmitted to the swallow counter.
• The divisor can be set to a value in the range 272 to 65,535.
When SNS in the serial data input is set to 0:
• The input frequency range is 0.5 to 10 MHz.
• The signal is transmitted to the 12-bit programmable divider.
• The divisor can be set to a value in the range 4 to 4,095.
This pin must be set high during serial data input (DI) to the
LC72144M, or during serial data output (DO).
Used for data synchronization during serial data input (DI) to
the LC72144M, or during serial data output (DO).
Used to input serial data transferred to the LC72144M from the
controller.
Used to output serial data transferred the controller from the
LC72144M.
The LC72144M power supply connection. Provide a voltage
between 4.5 and 5.5 V when the PLL circuit is in operation.
The power on reset circuit operates when power is first applied.
The LC72144M ground connection.
General-purpose I/O ports
The output circuits are open-drain circuits.
I/O-1 and I/O-2 are set to be input ports after the power on
reset. I/O-3 becomes an output port fixed at the low level.
These pins are switched between input and output by the I/O-1
to I/O-3 bits in the serial data transferred from the controller.

General-purpose I/O ports
The output circuits are complementary circuits.
These ports are set to be input ports after the power on reset.
These pins are switched between input and output by the I/O-0,
I/O-4, and I/O-5 bits in the serial data transferred from the
controller.
