HCMOS, 9X14,J-LEAD, VCXO
(SEE PART NUMBERING SYSTEM FOR PART NUMBER)
****ROHS COMPLIANT***
DESCRIPTION: A crystal controlled, HCMOS, highly stable oscillator, The output can be Tri-stated to facilitate
testing or combined multiple clocks. The device is contained in a sub-miniature, very low profile, leadless ceramic
SMD package with 6 or 4 gold J lead contacts. This miniature oscillator is ideal for today's automated assembly
environments.
