TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT CIRCUIT SILICON MONOLITHIC

TD6358P, TD6358N

FREQUENCY SYNTHESIZER FOR TV / CATV

TD6358P

DIP20-P-300-2.54A

TD6358N

SDIP20-P-300-1.78

Simple control bus               • 19bit serial input

Weight

5V single power supply operation

DIP20-P-300-2.54A

SDIP20-P-300-1.78

•  2.25g (Typ.)

•  1.029 (Typ.)

The TD6358P and TD6358N are single-chip frequency synthesizer ICs, which can organization high-performance frequency synthesizer systems in combination with a 4bit "CPU controller.

The TD6358P integrates high input sensitivity ECL prescaler, 1 2 L programmable counter, PI-L logic and bandswitch drive decoder in a DIP20-pin small package. The TD6358N is packaged in a shrink 20-pin package even smaller than TD6358P.

FEATURES

 High input sensitivity fin -80-100MHz : -24dBmW (500) (Min.) fin -O I-IGHz : -27dBmW (500) (Min.)

 Wide operating frequency          IGHz (Max.)

 3.2MHz basic oscillator and 50kHz frequency step

 Bandswitch driver                     4 channels

(Note) Handle with care as this product is weak at surge voltage.

FUNCTION

INTERFACE CIRCUIT

Test Pin 1

Low level : this will be in normal use operation mode when connected to GND or open.

In order to prevent a static breakdown, it will be more effective to connect to GND. High level : this will be in test mode when connected to V

20kQ

2

Enable Input

This is an enable pulse input terminal at normal use operation.

This will be a test mode select terminal of test mode by means of the pin 1 mode select pin. In order to prevent a static breakdown, it will be effective to connect in series a resistor of about 1kQ.

The pins 3 and 4 below are the same as this pin.

18kQ

3

Data Input

This is a data input terminal in normal mode.

In test mode 1 or 2, this will be a main counter output terminal. In test mode 3, this can be an external input terminal of comparison signal of phase comparator (a counter output terminal in normal mode).

18kQ

4

Clock Input

This is a clock pulse input terminal in normal mode.

In test mode 1 or 2, this will be an output terminal of reference signal whose crystal oscillator is divided by 29 .

In test mode 3, this can be an input terminal of external reference signal.

18kQ

5

Logic VCC

This is logic circuit power supply.

Connect a bypass condenser between this pin and pin 8.

Crystal Oscillation

This is a crystal oscillation terminal to make the reference signal.

Make sure to use the logic GND of pin 8 as this oscillates in a big amplitude (about 800mVp-p).

8

Logic GND

This is used for crystal oscillator GND as is logic GND.

Never wire this pin close to the high frequency GND of pin 16.

Comparator

Output

In normal use, this compares a high frequency wave input with frequency data and feeds back its difference by means of the supply pump.

Bandswitch

This can make the 4 band switching operate independently
