The ECS VXO-11 Series is a wide frequency,
tight tolerance, voltage controlled crystal
oscillator. Featuring a wide VCO range of
±200ppm, this oscillator is a serious
performer in applications such as wireless
communications, video data compression
or PLL.
FEATURES
• Wide voltage control range
• Wave form symmetry of 40/60%
• HCMOS or TTL output
• Industry standard DIP 14 pin lead spacing
