526N50025CTR

Oscillators Overview

The 526N50025CTR is a surface-mount Temperature Compensated Crystal Oscillator (TCXO) manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 50 MHz with a clipped sine wave output. The device requires a 2.5V supply voltage and draws a maximum current of 30mA during operation, reducing to 10µA in standby mode. It features a frequency stability of ±2.5ppm over the operating temperature range of -40°C to +85°C. The component is housed in a compact 3.2mm x 2.5mm 4-SMD, No Lead package with a maximum seated height of 1.20mm.

Oscillators Feature Summary

• Integrated temperature compensation for high frequency stability across wide industrial ranges
• Low power consumption with dedicated standby or power-down functionality
• Compact surface-mount footprint suitable for space-constrained designs
• Clipped sine wave output interface compatible with various digital inputs

Oscillators Applications

• Telecommunications base station timing references
• Industrial control system clock generation
• Automotive infotainment and navigation modules
• Portable electronic devices requiring precise timekeeping

Oscillators Procurement Notes

Verify the specific suffix 'CTR' confirms the tape and reel packaging configuration required for automated assembly processes. Ensure the operating voltage matches the 2.5V specification, as variations may exist within the series. Confirm that the ±2.5ppm stability requirement aligns with system jitter tolerance. Check RoHS compliance status for environmental regulations in the target market. Validate the MSL rating for soldering reflow profiles.

Oscillators Selection Notes

Select this component when a small form factor TCXO is needed with superior stability compared to standard XO types. The 50 MHz frequency is common for Ethernet and USB interfaces. Consider the 2.5V supply constraint against available board rails. The clipped sine wave output may require level shifting if the downstream logic expects HCMOS/TTL directly without buffering. Evaluate thermal management needs given the self-heating characteristics of TCXOs in sealed enclosures.

Oscillators Part Context

This part belongs to the 526 series of surface-mount oscillators from CTS-Frequency Controls. The series offers various frequencies and stability grades. Unlike the CA70 series which focuses on automotive AEC-Q200 qualification, the 526 series emphasizes compact size and low power. It differs from crystal resonators like the 416F series by providing a complete clock signal rather than a passive resonant element.

Oscillators Replacement Considerations

Direct parameter-equivalent substitutes within the same manufacturer series should be verified for pin compatibility and electrical specifications. Cross-manufacturer replacements require careful analysis of output waveform compatibility and supply current limits. Ensure any alternative maintains the ±2.5ppm stability and 50 MHz frequency accuracy.
