Features
The LM7001J and LM7001JM are PLL frequency
synthesizer LSIs for tuners, making it possible to make
up high-performance AM/FM tuners easily.
These LSIs are software compatible with the LM7000,
but do not include an IF calculation circuit.
The FM VCO circuit includes a high-speed
programmable divider that can divide directly.
Seven reference frequencies: 1, 5, 9, 10, 25, 50, and
100 kHz
Band-switching outputs (3 bits)
Controller clock output (400 kHz)
Clock time base output (8 Hz)
Serial input circuit for data input (using the CE, CL, and
DATA pins)

Notes on PLL IC Usage
1. PLL IC printed circuit board patterns
x Power supply pins
A capacitor must be inserted between the V
DD
and V
SS
power supply pins for noise exclusion. This capacitor
must be located as close as possible to these pins.
y FMIN and AMIN pins
The coupling capacitors must be located as close as possible to these pins.
z PD pins, low-pass filter
Since those are high-impedance pins, they are susceptible to noise. Therefore, the pattern should be kept as short
as possible and the area around this circuit should be covered by the ground pattern.
2. Initial states of the output ports (BO1 to BO3)
The initial states of the output ports after power is applied are undefined until data has been transferred.
In particular, it is possible for the BO1 and BO3 pins to output the internal clock, so data must be transferred as soon
as possible.
However, note that the LSI cannot accept data until the crystal oscillator is operating normally.

3. VCO
The VCO circuit is designed so that it does not stop oscillating even if the control voltage (Vtune) becomes 0 V.
(This is because the PLL circuit could become deadlocked if the VCO stopped.)
