1.3 GHz PLL for TV- and VCR- Tuner
U6209B
Description
The U6209B is a single chip PLL frequency synthesizer
with unidirectional I2C-bus control. This IC contains a
high frequency prescaler which can be switched off.
Features
D 1.3 GHz divide-by-8 prescaler integrated
(can be bypassed)
D 15 bit counter accepts input frequencies up to
170 MHz
D Programmable reference divider: divider by 512 or
1024
D m P-controlled by I2C-Bus (MC44818 data format
compatible)
D Five port outputs (open collector )
Five open collector switching outputs are available. The
U6209B has a programmable 512/1024 reference divider.
D Four addresses selectable at Pin 10 for multi-tuner
application
D 31.25 kHz ( –1.3 GHz ) / 3.90625 kHz ( –170 MHz )
tuning steps with 4MHz Xtal
D Electrostatic protection according to MILSTD 883
D SO16 small package

U6209B
Functional Description
The U6209B is programmed via a 2–wire I2C bus data
format. The three bus input Pins 4, 5, 10 are used as SDA,
SCL and address select inputs. The data includes the
scaling factor SF (15 bit) and port output information.
There are some additional functions included for testing
of the device.
I2C - Bus Description
The U6209B is controlled via a 2-wire I2C bus format by
feeding data and clock signals into the SDA and SCL lines
respectively. The table ‘I2C–BUS DATA FORMAT’
describes the format of the data and shows how to select
the device address by applying a voltage at pin 10. When
the correct address byte has been received, the SDA line
is pulled low by the device during the acknowledge
period, and then also during the acknowledge periods,
when additional data bytes are programmed. After the
address transmission (first byte), data bytes can be sent to
the device. There are four data bytes requested to fully
program the device. The programmable divider latch is
loaded after the 8th clock pulse of the second divider byte
PDB2, the control and the port register latches are loaded
after the 8th clock pulse of the control byte CB1 respec-
tively post byte CB2. The table ‘I2C-BUS PULSE
DIAGRAM’ shows some possible data transfer exam-
ples.
The programmable divider bytes PDB1 and PDB2 are
stored in a 15-bit latch and control the division ratio of the
15-bit programmable divider. The control Byte CB1
enables the control of the the following special functions:
D 5I-bit switches between low and high charge pump
current
D T1-bit enables divider test mode when it is set to
logic 1
D T0-bit enables the charge pump to be disabled when
it is set to logic 1
D RD1 and RD2-bit allow selection of the reference
divider ratio
D PSC–bit switches prescaler off when it is set to
logic 0
D OS-bit disables the charge pump drive amplifier out-
put when it is set to logic 1.
When T1 is set to logic 1, the programmable divider out-
put signal is switched to pin 7 and the reference divider
output signal is switched to pin 6. The OS-bit function
disables the complete PLL function. This enables tuner
alignment by supplying the tuning voltage directly via the
30-V supply voltage of the tuner. The control byte CB2
programs the port outputs P0-4; a logic 0 for high
impedance output (off) and a logic 1 for low impedance
output (on).
