356C433B4I2T

Oscillators Overview

The CTS-Frequency Controls 356C433B4I2T is a Voltage Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 43.35 MHz. It utilizes a crystal resonator and provides an HCMOS output format. The device supports enable/disable functionality and operates on a 2.5V supply voltage. Key electrical parameters include a frequency stability of ±30 ppm and an absolute pull range of ±50 ppm. The unit consumes a maximum supply current of 65 mA during operation and 22 mA in the disabled state. It is housed in a compact 6-SMD, no-lead package with dimensions of 7.00 mm x 5.00 mm x 1.85 mm.

Oscillators Feature Summary

• Voltage-controlled frequency adjustment via control voltage input
• Integrated enable and disable control function for power management
• HCMOS logic output format compatible with standard digital interfaces

Oscillators Applications

• Precision clock generation in communication systems
• Frequency synthesis circuits requiring tunable reference signals
• Data transmission equipment needing stable timing references

Oscillators Procurement Notes

Verify that the specific suffix 'I2T' corresponds to the intended temperature range, packaging configuration, and electrical specifications as defined by the manufacturer's datasheet. Ensure the design accommodates the 2.5V supply requirement and the physical footprint of the 6-SMD no-lead package. Confirm compatibility with the required HCMOS load conditions and signal integrity requirements for the target application environment.

Oscillators Selection Notes

Select this component when a tunable oscillator with ±30 ppm stability is required at 43.35 MHz. The 356C series offers a balance of size and performance with a 7.0x5.0mm footprint. Consider the HCMOS output if single-ended logic levels are sufficient; otherwise, evaluate LVDS or LVPECL variants within the same family for differential signaling needs. Ensure the control voltage range aligns with the system's ability to modulate the frequency within the ±50 ppm pull range.

Oscillators Part Context

This part belongs to the CTS 356C series of VCXOs, designed for surface-mount applications. The series provides various output formats and frequencies while maintaining consistent mechanical dimensions. The 356C433B4I2T specifically targets applications requiring precise frequency tuning within a narrow stability window, leveraging the inherent properties of crystal resonators for long-term reliability.

Oscillators Replacement Considerations

Direct substitutes may include other 356C series parts with matching frequency and output format, such as 356C433B3C2T, though supply voltage and package variations must be verified. Cross-reference with equivalent VCXOs from other manufacturers ensuring identical pinout, voltage, and electrical characteristics.
