Description
The 5V S1800, S1850 and 3.3V S1803 are
crystal-controlled, low-current oscillators
providing precise rise and fall times to
drive high speed CMOS and TTL loads.
The sub-miniature, very low profile lead-
less ceramic packages have gold-plated
contact pads, ideal for today's pick-and-
place SMT environments. The S1850 is
a high output load version available to
80 MHz.
Applications & Features
• Sub-miniature, 1.1 mm high ceramic
package ideal for SMT applications
• 10µA max standby mode on S1800
and S1803
• Tight Stability, low power, and low
profile ideal for 802.11 applications
• Available as 3.3V and 5V versions
LVCMOS, HCMOS, TTL compatible
• Perfect for PC's; notebook, palmtop
computers; portable applications;
PCMCIA cards;disc drives. Anywhere
small size, low power, surface mount-
ability are a priority
• Available on tape & reel; 16mm tape,
1000pcs per reel
