Quartz Blanks Oscillators | TKD

TKD Quartz Blanks Oscillators pair high-quality quartz resonators with integrated oscillator circuits to deliver dependable CMOS timing. Offered in compact standard packages with tight frequency tolerance, they provide a cost-effective alternative for consumer and industrial clock generation.

Ranges of Quartz Blanks Oscillators

Built on premium quartz blanks, these oscillators deliver stable frequencies with tight initial tolerance and low aging. Compact ceramic packages, CMOS output and wide frequency coverage make them a practical choice for general-purpose timing across many applications.

Quartz Blank Characteristics and Oscillator Frequency Design

Quartz blank quality

High-grade blanks with controlled cut angles and surface finish ensure accurate frequency, low motional resistance and stable start-up across the operating temperature range.

Frequency design

The oscillator frequency is set by the blank's mechanical resonance; designers choose the nominal frequency and tolerance grade to match the system clock budget.

Aging and drive

Proper drive-level control keeps the blank vibrating in its linear region, minimizing aging and frequency drift over the product lifetime.

Circuit Matching Considerations for Quartz-Blank Oscillators

Load capacitance

Set the external load capacitance close to the specified value so the oscillator runs at the intended frequency; excessive mismatch shifts the output frequency and degrades stability.

Start-up margin

Ensure the negative resistance of the circuit exceeds three to five times the blank's motional resistance for reliable, fast start-up.

Parasitic control

Keep PCB traces short and clean around the oscillator, and avoid high-capacitance stubs, to prevent parasitic loading from altering the resonant frequency.
