Overview
The LC72151V is a PLL frequency synthesizer for car
audio systems. It can implement high-performance
multifunction tuners such as RDS tuners and features a
fast locking circuit.
Functions
High-speed programmable divider
— FMIN: 10 to 160 MHz: Pulse swallower type
— AMIN: 2 to 40 MHz: Pulse swallower type
0.5 to 10 MHz: Direct division type
IF counter
— HCTR: 0.4 to 25 MHz: for FM IF count
— LCTR: 10 to 500 kHz: for AM IF count
1.0 to 20
× 103 Hz: for frequency
measurement
Reference frequency
— One of 11 frequencies may be selected (when a
10.25 or 10.35 MHz crystal is used)
50, 30*, 25, 12.5, 10, 9*, 6.25, 5, 3.125, 3*, 1 kHz
Note: Cannot be used when a 10.25 MHz crystal is
used
