Hka lum ai lam hpe gram lajang ai Crystal Oscillator (TCXO) ni hpe gara hku garan ginhka da ai kun?
Temperature Compensated Crystal Oscillator (TCXO) ngu ai gaw, n bung ai nbung laru masa hta, n galai shai ai frequency pru ai lam hpe n-gun n rawng hkra galaw ya ai nbung laru langai mi re. Dai gaw grup yin nbung katsi ai lam galai shai ai lam a oscillation frequency ntsa hkra machyi ai lam hpe shayawm na matu nbung katsi ai lam hpe gram lajang ai circuit hpe bang da ai, grup yin amyu myu hta -htuk manu ai aten ladaw masat kumla ni hpe hkam la lu na matu. TCXO ni hpe madung hku nna, hkrak hkrak hka wa ai, n hkrak hka wa ai, digital hka wa ai ngu ai daw masum hku garan nna galaw ai.
TCXO ni a arawn alai ni
High Stability: Nbung laru kaba ai shara hta ngang grin ai frequency pru wa ai lam hpe jaw ya nna, nbung laru galai shai ai lam a majaw jak a bungli galaw ai lam hta hkra machyi ai lam hpe shayawm ya lu ai.
High Precision: Aten hpe grai hkrak hkra galaw ra ai application ni a matu htuk manu ai, -htuk manu ai ahkying masat kumla ni hpe jaw ya ai.
N-gun n law ai: Mobile device ni hte battery-n-gun lang ai application ni hta n-gun n law ai hku jai lang na matu law law lang galaw da ai rai nna, battery prat hpe galu kaba hkra galaw da ai.
Low Phase Noise: TCXO design nkau mi gaw low phase noise arawn alai ni hpe mung jaw ya ai, dai gaw signal n-gun n-gun hpe hkam sha chye ai matut mahkai ladat ni hte kaga application ni a matu grau ahkyak ai.
Direct hka wa na TCXO
The direct compensation TCXO utilizes a temperature compensation circuit composed of thermistors and resistive-capacitive elements, connected in series with the quartz crystal resonator in the oscillator. Htingbu htingbyen ni a nbung katsi ai lam galai shai wa ai shaloi, thermistor a ninghkap ai lam hte crystal a bung ai series capacitance ni gaw dai hte maren galai shai wa nna, dai hku nna oscillation frequency a nbung katsi ai lam hpe shayawm kau ya ai (sh) shayawm kau ya ai. Ndai htingnut ai ladat gaw asan sha re ai circuit, manu n law ai, printed circuit board (PCB) a galu kaba ai lam hte shara ra ai lam ni hpe shayawm ya ai zawn re ai akyu ni hpe jaw ya ai majaw, n-gun n law ai, n-gun n law ai-voltage, n-gun n law ai-current ni hpe jai lang na matu grai htuk manu ai. Raitim, ±1 ppm hta grau kaja ai crystal oscillator hkrak ai lam a matu ra kadawn ai lam ni hpe n lu galaw na re.
N hkrak ai hku hka wa ai TCXO
Analog Indirect Compensation: Thermistor zawn re ai nbung hpe hkam sha lu ai arung arai ni hpe jai lang nna, nbung hpe n-gun galai shai ai circuit hpe galaw ai. Dai kaw na pru wa ai n-gun hpe varactor diode langai mi hpe kristal resonator hte series hku matut da ai. Dai n-gun n-gun n-rawng ai n-gun n-rawng ai n-gun n-rawng ai hpe gram lajang ya ai. Ndai htingnut ai ladat gaw ±0.5 ppm a tsaw ai hkrak ai lam hpe lu la mai ai raitim 3V npu hta bungli galaw ai application ni hta gaw shadawn sharam sha rai na re.
Digital Indirect Compensation: Analog htingnut ai lam hpe gram lajang ai hta, nbung katsi ai hpe galai shai ai circuit ngut ai hpang, analog-to -digital (A/D) de galai shai ai hte digital{2}}de - analog (D/A) de galai shai ai circuit hpe jat bang ai.

Ndai ladat gaw, nbung katsi ai hpe shi hkrai shi gram lajang ya lu ai majaw, crystal oscillator a matu laklai ai hku nna, n-gun kaba ai frequency hpe lu la shangun ai. Raitim, hka wa na circuit gaw grai sawng ai hte manu dan ai.
Digital TCXO
Digital TCXO ni gaw, nbung katsi ai hpe hkrak hkrak gram lajang na matu, digital signal galaw ai hpaji hpe jai lang ma ai.
