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
