Overview
The LC72147V is a PLL frequency synthesizer for car
audio systems. It can implement high-performance
multifunction tuners and features a crystal oscillator
circuit that supports AM up-conversion, a fast locking
circuit, an A/D converter, and an LA1783/1750 IF counter
buffer control pin.
Functions
High-speed programmable divider
— FMIN: 10 to 180 MHz: Pulse swallower type
IF counter
— HCTR: 0.4 to 25 MHz: Frequency measurement
Crystal oscillator: One of the following 4 frequencies
may be selected: 10.35, 10.25, 7.2, and 4.5 MHz
Reference frequency
— One of 12 frequencies may be selected (when a 7.2
or 4.5 MHz crystal is used)
100*1, 50, 30*2, 25, 12.5, 6.25, 3.125, 10, 9*2, 5, 3*2,
1 kHz
Notes: 1. Cannot be used when a 10.35 or 10.25 MHz
crystal is used
2. Cannot be used when a 10.25 MHz crystal
is used
Phase comparator
— Supports dead band control
— Built-in unlock detection circuit
— Sub-charge pump for fast locking
— Built-in deadlock clearing circuit
Built-in MOS transistor for forming an active low-pass
filter
I/O ports — General-purpose I/O: 5 pins
— Output: n-channel: 3 pins, CMOS: 2 pins
— IFBC pin (LA1783/1750 IF counter buffer control
pin)
Serial data I/O
— Supports communication with the controller in the
CCB format.
Operating ranges
— Supply voltage (VDD): 4.5 to 6.5 V
— Built-in regulator voltage (Vreg): 3.0 V (±10%)
— Operating temperature: –40 to +85°C
Package
— SSOP-24
