C T S
F R E Q U E N C Y P R O D U C T S
Features:
• Standard miniature surface mount footprint
• Frequency range 1.5 to125 MHz
• Frequency stability: 100 ppm standard; 50 ppm and 25 ppm available
• PCMCIA Type II & III
compatible
• Low voltage option available
• CMOS/TTL compatible
• Fibre Channel Compliant
• Gigabit Ethernet Compliant
• Tri-State Output standard
• Tape and reel packaging (16mm)
The CTS CB3 is a ceramic packaged Clock oscillator offering reduced size and enhanced stability. The small
size means it is perfect for any application. The enhanced stability means it is the perfect choice for today’s
communications applications that require tight frequency control. Low voltage options are also available.
Tristate control is also standard.
