HCMOS
A 5V crystal controlledꢀ low currentꢀ low
jitter and high frequency oscillator with
precise rise and fall times demanded in
networking applicationsꢀ such as Gigabit
EthernetandFibreChannel. Thetri-state
function on the NTH enables the output
to go high impedance. Deꢁice is pack-
aged in a 14 or an 8-pin DIP compatible
resistance weldedꢀ all metal grounded
caseꢀ to reduce EMI. True SMD DIL 14
ꢁersion also aꢁailableꢀ utilizing new
adaptor technology (see separate data
sheet for package dimensions)
