CERAMIC

RESONATORS

SMD 1.79 ~ 50.00 MHz

ZTAC/ZTTC Series is The Smallest Chip

Ceramic Resonators (Murata CSAC/CSTC Compatible)

Preview

Previously, only higher cost quartz crystal resonators

were considered for CAN bus application, due to tighter

frequency tolerance requirements than for traditional

automotive bus applications. Nowaday, Token utilizes the

latest ceramic piezo technology freeing the design engineers

from having to use these higher cost components and still

achieve desired reliability and performance targets.

Token ZTAC and ZTTC series are the SMD ceramic

resonators that meet the frequency tolerance ±0.5%,

temperature tolerance ±0.3% ~ ±0.4%, and aging

tolerance ±0.3%. The ZTAC and ZTTC covers the frequency range of 1.79 MHz to 50.00 MHz. ZTTC series

features a built-in load capacitance. This feature eliminates any need for external loading capacitors and reduces

component count, increases reliability and reduces size.

The ZTACE×MG (3.2 x 1.3 mm) with (max) proﬁle 1.0 mm and ZTACW×MX (2.5 x 2.0 mm) with (max)

proﬁle 1.5 mm are the smallest resonators for their respective frequency ranges. All ZTAC and ZTTC series are

surface mount devices (SMD) with operating temperature range is -20°C to +80°C.

Tolerance is the main key characteristics to evaluate for a resonator. The total tolerance is the addition of the

initial tolerance, temperature tolerance and aging tolerance. Tighter tolerances are possible through design

advancements, material reﬁnement and manufacturing techniques. Token’s design and material improve the

temperature and aging characteristics of the resonator. Token’s manufacturing ability sort to tighter initial

tolerances.

Custom parts are available on request. Token will also produce devices outside these speciﬁcations to meet

speciﬁc customer requirements,

please contact Token sales for more information.

Beneﬁt Features :

- High reliability chip resonator with high temperature withstanding ceramic case.

- Ultra-miniature size is suitable for compact equipment high mounting density.

- Low proﬁle, Reﬂow solderable, Excellent solderability.

Applications :

- Car accessories.

- PDAs, PC peripherals.

- Camcorders, Digital cameras.

(ZTAC/ZTTC) Resonator Application - Oscillation Circuit for MOS IC

Feedback Resistor (R = 1MΩ):

A Feedback Resistor is used to determine the oscillation circuit bias. The feedback resistance will contrib-

ute to instability if it is too large by reducing feedback. Conversely, if it is too small, increases in current

will be realized thereby reducing gain. Recent developments in IC design allows for the integration of the

feedback resistor in many cases.

Bias resistor (Rb optional):

A Bias Resistor can be utilized in the Ceramic Resonator Oscillation Circuit to change the bias point when

a reduction in IC gain is required, or to suppress unstable oscillation. This may be especially considered

when a 3 stage buffered IC, or TTL IC, is used.

Damping Resistor (Rd optional):

Abnormal harmonic oscillation can be suppressed using a dampening resistor. The dampening resistor and

load capacitors work together as a low-pass ﬁlter to reduce gain in the MHz range of oscillation.

Loading Capacitor (C1 & C2)

The stability of the oscillation circuit is mainly determined by the C1 & C2 values. If the load capacitance

is too small, unstable oscillation will occur because of oscillation waveform distortion. If too high, a stop

in oscillation can be expected. When comparing the same IC, oscillation circuits with lower frequencies

require higher capacitance. Token Engineers can help with the circuit design if needed.

(ZTAC/ZTTC) Resonator Optimization - IC Evaluations

Tolerance is determined by the design of the resonator. However stability and correlation is determined by

the IC evaluation. The microcontroller is evaluated with the ceramic resonators to determine the best pos-

sible circuit conditions to achieve stability and stable oscillation.

In addition, frequency correlation is measured to meet the tight initial frequency tolerance required. For the

tight tolerance resonators the IC evaluation must be completed on the ﬁnal circuit board layout. The ﬁnal

circuit boards provide the most accurate measurement of the frequency correlation.

This measurement will account for the effects of stray capacitance on the oscillation frequency. Once the

correlation is determined the frequency of the resonator is adjusted to compensate for the correlation.
