BS-250.000MBC-T

Oscillators Overview

The BS-250.000MBC-T is a surface-mount crystal oscillator manufactured by TXC Corporation, designed for high-frequency timing applications. It operates at a nominal frequency of 250 MHz and utilizes LVPECL (Low Voltage Positive Emitter Coupled Logic) output configuration to ensure signal integrity in high-speed digital systems. The device is housed in a compact 7 mm x 5 mm six-SMD, no-lead package, facilitating efficient PCB layout and automated assembly processes. It functions on a single 3.3 V supply voltage with a typical current consumption of 80 mA. The oscillator includes an enable/disable function for power management flexibility. Frequency stability is specified at ±100 ppm over the operating temperature range, ensuring reliable performance in demanding electronic environments.

Oscillators Feature Summary

• LVPECL differential output interface for high-speed data transmission
• Integrated enable/disable control functionality
• RoHS compliant lead-free construction

Oscillators Applications

• High-speed FPGA timing reference
• Data acquisition systems
• Telecommunications equipment clocking

Oscillators Procurement Notes

Verify the complete part number including the suffix '-T' to confirm tape-and-reel packaging availability. Ensure the design-in process accounts for the specific LVPECL load requirements and 3.3 V supply constraints. Confirm that the 250 MHz frequency aligns with the target system's clock distribution network specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 250 MHz clock source with LVPECL outputs is required for high-speed logic interfaces. Consider the 7x5 mm footprint for space-constrained designs. Evaluate the ±100 ppm stability against system jitter budgets. Compare against alternative packages if board real estate permits different form factors while maintaining electrical compatibility.

Oscillators Part Context

This oscillator belongs to the BS series from TXC Corporation, which focuses on standard surface-mount crystal oscillators. The series provides various frequencies and output types for general-purpose timing needs. The BS-250.000MBC-T specifically addresses the demand for 250 MHz signals in modern digital circuits requiring low-voltage differential signaling capabilities.

Oscillators Replacement Considerations

Direct substitutes include other 250 MHz LVPECL oscillators in 7x5mm packages from manufacturers such as Epson or SiTime, provided pinout and electrical parameters match exactly.
