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.
