Wide Temperature Oscillators Manufacturer

TKD Wide Temperature Oscillators deliver stable timing across −40 °C to +125 °C, meeting the demands of automotive, industrial and outdoor applications. Available in compact packages with CMOS output and ±50 ppm stability, they keep clocks reliable under harsh thermal conditions.

Ranges of Wide Temperature Oscillators

Engineered for extreme thermal environments, these oscillators hold tight frequency stability from −40 °C to +125 °C while consuming little power. Compact packages, robust construction and CMOS output make them ideal for automotive ECUs, industrial controllers and outdoor equipment.

Maintaining Frequency Stability Across Wide Temperature Ranges

Temperature-swept stability

Wide-temperature SPXOs are characterized across the full −40 °C to +125 °C range, holding frequency deviation within ±50 ppm so system timing budgets remain valid in any environment.

Crystal cut design

AT-cut quartz blanks with optimized angles minimize frequency shift over temperature, delivering predictable, repeatable behavior for automotive and industrial duty.

Thermal shielding

Internal package construction and controlled mounting reduce thermal gradients across the device, avoiding abrupt frequency jumps during rapid temperature changes.

Selecting Wide-Temperature Oscillators for Variable Operating Conditions

Define the operating envelope

Determine the actual ambient range and system self-heating first, then choose a stability grade that covers the combined temperature effect with margin.

Match frequency and load

Select the correct nominal frequency, load capacitance and CMOS drive so the oscillator works with the target MCU or SoC clock input without extra buffering.

Reliability factors

For harsh environments, verify shock, vibration and solder-joint robustness, and request AEC-Q or extended-temperature qualification data where the application demands it.
