TTL Compatible Enable/Disable

HA-1210 Series

Description

The HA-1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for

bus connected systems. Supplying Pin 1 of the HA-1210 units with a logic “1" enables the output on Pin 5.

In the disabled mode, Pin 5 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

• Low Jitter

• High Q Crystal actively tuned oscillator circuit

• Will withstand vapor phase temperatures of 253°C • Power supply decoupling internal

for 4 minutes maximum

• Space-saving alternative to discrete component

oscillators

• High shock resistance, to 3000g

• All metal, resistance weld, hermetically sealed

package

• No internal PLL avoids cascading PLL problems

• Low power consumption

• Gold plated leads - Solder dipped leads available

upon request

• RoHS compliant, Lead Free Construction

(unless solder dipped leads are supplied)
