Oscillators are electronic or electromechanical devices that are used for generating alternating or periodic electrical signals usually at audio/RF frequencies. MX575ABH250M000 is a compact high performance Voltage Controlled Crystal Oscillator (VCXO) designed for frequency control and references. It is widely used in communication systems which require low jitter clock references, such as Ethernet and Sync-E networks.

Application Field

MX575ABH250M000 is suitable for use in communication systems, mobile data networks, storage systems, video/audio applications and embedded controllers. It is widely used in many applications such as WIFI base stations, repeaters, access points, server storage systems, security cameras, automotive and telematics products, drones, industrial control, and medical equipment.

The combination of very low jitter performance (0.20ps Typ RMS) with an exceptionally narrow tunable range of 6.25MHz makes the device well suited for applications requiring a precise and stable clock frequency, such as base station timing and synchronization systems.

Working Principle

MX575ABH250M000 utilizes a temperature compensated crystal oscillator (TCXO). It is a quartz crystal oscillator which employs a negative temperature coefficient of frequency (NTCF) quartz crystal to compensate for the effects of temperature variations on crystal oscillator stability. The oscillator includes a voltage control input to vary the frequency within the range specified, up to ±12.5MHz. This feature eliminates the need for a costly Frequency Synthesizer and reduces the effort required for system design.

The newly designed three-state S / PDIF output circuit has a ground reference output current that reduces EMI and RFI problems, making it a smart choice for applications requiring precise clock signal transmission.

The device includes an ENABLE pin that allows the output signal to be disabled when the frequency is adjusted. Additionally, the BREAKDOWN voltage can be adjusted to prevent the device from entering ENABLE mode. This feature is useful for protecting circuits from high frequency radiation in the event of sudden voltage spikes.

MX575ABH250M000 is a reliable and cost-effective Frequency Control Device which is ideal for applications where frequency control and stability are critical. Along with the exceptional jitter performance, high-end power supply rejection ratio (PSRR) and fast voltage control response, it is perfectly suited for timing and synchronization in high demand networks.
