Description

A crystal controlled, low current, low jitter and high frequency oscillator with precise rise and fall times demanded in high performance networking, telecom and processor applications. The tri-state function enables the output to go high impedance. Available in a 14 or an 8 pin DIP compatible, resistance welded, all metal case. Pin 7 (or Pin 4) is grounded to case to reduce EMI. See photo above for new, full size metal package with a true SMD adapter. For this package option select option S in part number builder.
