7X-38.400MBB-T

Oscillators Overview

The 7X-38.400MBB-T is a standard clock oscillator manufactured by TXC Corporation, operating at a frequency of 38.4 MHz. It utilizes CMOS output format and requires a supply voltage of 3.3 V. The component exhibits a frequency stability of ±50 ppm within an operating temperature range of -10°C to +70°C. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm and a height of 0.8 mm.

Oscillators Feature Summary

• Generates precise 38.4 MHz timing signals using CMOS output logic for digital circuit integration.
• Provides stable frequency performance with ±50 ppm tolerance across the specified industrial temperature range.
• Features a low-profile surface-mount design suitable for space-constrained electronic assemblies.

Oscillators Applications

• Standard clock generation for microprocessors and microcontrollers
• Timing reference for communication interfaces such as UART and SPI
• Clock source for embedded systems requiring 3.3V operation

Oscillators Procurement Notes

Verify that the required operating temperature range aligns with the component's specified -10°C to +70°C limit, as this differs from wider industrial ranges. Confirm that the system power supply strictly maintains the 3.3V requirement to ensure correct CMOS output levels. Ensure PCB layout accommodates the 4-SMD No Lead footprint dimensions accurately to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this model when a 38.4 MHz CMOS oscillator is required for 3.3V logic systems. Choose this part over wider temperature variants if the application environment remains within -10°C to +70°C. Consider the ±50 ppm stability specification against system jitter requirements. Verify compatibility with the 4-SMD No Lead package size compared to alternative packages like 7V or 8WE series components.

Oscillators Part Context

This component belongs to the 7X series of standard clock oscillators from TXC Corporation. The series offers various frequencies and stability options in a small surface-mount package. The 7X-38.400MBB-T specifically targets applications needing a reliable 38.4 MHz clock source with moderate stability requirements in a compact form factor.

Oscillators Replacement Considerations

The 7X-38.400MBC-T is a confirmed substitute offering similar specifications but with ±100 ppm frequency stability. Both parts share the same 38.4 MHz frequency, 3.3V supply, CMOS output, and 4-SMD No Lead package, allowing for direct pin-compatible replacement if the stability tolerance permits.
