TTL Compatible Enable/Disable

HS-1200/1210 Series

             

         

                                                                                                

Description

The HS-1200/1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible

signals for bus connected systems.  Supplying Pin 1 of the HS-1200 units with a logic “0" enables the output

on Pin 8.  Alternately, supplying pin 1 of the HS-1210 units with a logic “1" enables its Pin 8 output.  In the

disabled mode, Pin 8 presents a high impedance to the load.  All units are resistance welded in an all metal

package, offering RFI shielding, and are designed to survive standard wave soldering operations without

damage.  Insulated standoffs to enhance board cleaning are standard.

Features

• Wide frequency range– 0.5MHz to 36MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C 

     for 4 minutes maximum

• Space-saving alternative to discrete component      

   oscillators

• High shock resistance, to 3000g   

• All metal, resistance weld, hermetically sealed        

     package

• Low Jitter

• High Q Crystal actively tuned oscillator circuit

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• Low power consumption

• Gold plated leads - Solder dipped leads available
