Overview
The LC72121 and the LC72121M and the LC72121V are
high input sensitivity (20 mVrms at 130 MHz) PLL
frequency synthesizers for 3 V systems. These ICs are
serial data (CCB) compatible with the LC72131, and
feature the improved input sensitivity and lower spurious
radiation (provided by a redesigned ground system)
required in high-performance AM/FM tuners.
Functions
High-speed programmable divider
— FMIN: 10 to 160 MHz ... Pulse swallower technique
(With built-in divide-by-2
prescaler)
— AMIN: 2 to 40 MHz ... Pulse swallower technique
0.5 to 10 MHz ... Direct division technique
IF counter
— IFIN: 0.4 to 12 MHz ... For AM and FM IF counting
Reference frequency
— One of 12 reference frequencies can be selected
(using a 4.5 or 7.2 MHz crystal element)
1, 3, 5, 9, 10, 3.125, 6.25, 12.5, 15, 25, 50, or 100
kHz
Phase comparator
— Supports dead zone control.
— Built-in unlocked state detection circuit
— Built-in deadlock clear circuit
An MOS transistor for an active low-pass filter is built
in.
I/O ports
— Output-only ports: 4 pins
— I/O ports: 2 pins
— Supports the output of a clock time base signal.
Operating ranges
— Supply voltage: 2.7 to 3.6 V
— Operating temperature: – 40 to 85°C
Package
— DIP22S, MFP24S, SSOP24
Comparison with the LC72131/M
— Serial data compatible (CCB)
— Identical pin functions
— Two V
SS
pins were added.
— The DIP version is pin compatible (V
SS
pins were
inserted as the DIP22S NC pins.)
— The MFP product provides a modified pin
assignment (The MFP20 package was replaced by
an MFP24 package, and extra V
SS
pins were added.)
— The SSOP24 is a newly developed package that has
the same pin assignment as the MFP24S product.
