Circuit Description
The U6209B is a single-chip PLL designed for TV and
VCR receiver systems. It consists of a bridgeable
divide-by-8 prescaler with an integrated preamplifier, a
15-bit programmable divider, a crystal oscillator and a
reference divider with two selectable divider ratios
(512 / 1024), and a phase/frequency detector together
with a charge pump which drives the tuning amplifier.
Only one external transistor is required for varactor-line
driving. The device can be controlled via I
2
C bus format.
There are four programmable addresses selectable,
programmed by applying a specific input voltage to the
address-select input, enabling the use of up to four
synthesizers in a system. Five open collector output port
functions are included which are capable of sinking at
least 10 mA.
Oscillator frequency calculation:
fvco = PSF x SF x frefosc / 1024
fvco: Locked frequency of voltage controlled oscillator
PSF : Scaling factor of prescaler (1 or 8)
SF :
Scaling factor of programmable 15-bit divider
frefosc :Reference oscillator frequency:
3.2/4 MHz crystal or external reference frequency
In addition, there are port outputs available for band-
switching and other purposes.
Application
A typical application is shown on page 10. All input /
output interface circuits are shown on page 9.
Some special features which are related to test- and
alignment procedures for tuner production are explained
together within the following I
2
C bus mode description.
