TSM32-H50CQ33ST-20.000M-TR

Oscillators Overview

The TSM32-H50CQ33ST-20.000M-TR is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc., designed for surface-mount applications. It operates at a nominal frequency of 20.000 MHz with an HCMOS output type. The device requires a supply voltage of 3.3V and features an enable/disable function. Key electrical parameters include a maximum supply current of 30mA and a frequency stability of ±50ppm. The operating temperature range extends from -40°C to +85°C. The component is housed in a compact 4-SMD, No Lead package, specifically a 4-VDFN footprint measuring 3.20mm x 2.50mm with a maximum height of 1.20mm.

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure correct voltage, frequency, and package specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and availability. Ensure that the enable/disable pin configuration matches your system design before procurement.

Oscillators Selection Notes

Select this component when a 20MHz HCMOS clock source is required within a -40°C to +85°C industrial temperature range. Consider the ±50ppm frequency stability for general timing applications rather than high-precision metrology. Evaluate the 3.3V supply requirement and 30mA max current consumption against your power budget. The small 3.2x2.5mm package is suitable for space-constrained PCB layouts.

Oscillators Part Context

This oscillator belongs to the TSM32 series, which offers ultra-miniature SMD CMOS oscillators. The series provides various frequencies and supply voltages, including 1.8V and 3.3V options. The TSM32 family is characterized by its small physical dimensions and standard HCMOS outputs, targeting applications where size and cost efficiency are critical factors in clock generation.

Oscillators Replacement Considerations

No direct public substitute part numbers are explicitly confirmed for this specific model in the provided data. For discontinued Epson VG-1201CA models, Transko suggests the TSMV series as a drop-in replacement. Verify compatibility with alternative MEMS or crystal oscillators based on pinout and electrical specifications.
