The 1XTQ15600UBB is a SMD oscillator (XO) SMD-5032_4P RoHS manufactured by KDS. It is a crystal oscillator which works on a quartz crystal and uses an internal oscillation circuit to generate frequencies at a very high accuracy. This oscillator is housed in a small, surface mount package, allowing it to be integrated into compact devices. It also meets RoHS directives, meaning that no materials dangerous to human health and environment are used in its production. In addition, it has a frequency range of 15--600MHz and is a low-power consumption device with a Frequency Tolerance of ± 50ppm/-10+70°C. This high accuracy, low power device is ideal for use in wireless mobile phones, wifi and bluetooth systems, high-speed industrial and automotive systems, and many other applications.
