Product Overview
Kyocera KXO-01 series TTL drive crystal clock oscillator running at 30.000 MHz. Housed in a full-size rectangular metal can with a 14-pin DIP footprint. Outputs a TTL-level square wave from a single 5V DC supply. A self-contained active oscillator — no external crystal circuit required. Standard pinout: Pin 1 NC, Pin 7 Ground, Pin 8 Output, Pin 14 +5V DC.

Frequently Asked Questions
Will this fit a half-size or 8-pin oscillator socket?
No. This is a full-size rectangular metal can with a 14-pin DIP footprint. It will not fit a half-size square 8-pin socket. Verify your board's oscillator footprint before ordering.
Is this compatible with 3.3V systems like an ESP32 or Raspberry Pi?
No. This part requires a 5V DC supply and outputs TTL-level signals. Connecting it directly to a 3.3V logic board risks damage. A level shifter is required for use in 3.3V environments.
Can this replace a passive 2-pin crystal?
No. This is an active oscillator with its own internal circuitry. It cannot substitute for a passive 2-pin crystal in a Pierce or similar oscillator circuit.
Are the pins full length, or have they been clipped?
These are unused NOS units with full-length pins — not pulled from previous installations. They are suitable for socketing or direct through-hole mounting.
What is the frequency stability?
±100 ppm, consistent with the KXO-01 series standard specification.
Verify your board's oscillator socket type — full-size 14-pin DIP — before purchase. Datasheet available from Kyocera/AVX for full electrical specifications.
