HA121B - (HA121x) Crystal Clock Oscillators

This page provides the datasheet information for the HA121B, a member of the HA1211 (HA121x) Crystal Clock Oscillators family.

Datasheet Summary

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.

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 inter.

CRYSTAL CLOCK OSCILLATORS TTL Compatible Enable/Disable Data Sheet 8820B Rev. L 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.
