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 I2C 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 I2C bus mode description.
