Frequently Asked Questions

What types of crystal oscillators does XGHC offer?

XGHC offers four main types of crystal oscillators: (1) SPXO (Standard Crystal Oscillator) - basic oscillator with ±25-100ppm stability, lowest cost

(2) TCXO (Temperature Compensated) - includes temperature compensation circuit for ±0.5-2.5ppm stability

(3) VCXO (Voltage Controlled) - frequency can be adjusted by control voltage for synchronization

(4) OCXO (Oven Controlled) - heated crystal chamber for ±10-50ppb stability, highest precision. SPXO is suitable for general applications. TCXO is ideal for communication and GPS. VCXO is used for clock synchronization. OCXO is for precision timing and instrumentation.

Choose SPXO for cost-sensitive applications. Choose TCXO for better temperature stability. Choose VCXO for frequency control. Choose OCXO for highest precision.

When should I use a crystal oscillator instead of a crystal resonator?

Use XGHC crystal oscillators instead of resonators when: (1) Faster time-to-market - no oscillator circuit design needed

(2) Better frequency stability - active compensation in TCXO/OCXO

(3) Guaranteed oscillation - factory-tested reliable start-up

(4) Space savings - no external oscillator components

(5) Higher frequencies - easier to achieve >50MHz

(6) Multiple outputs - some oscillators provide multiple clock phases

(7) Specific output format - LVDS, LVPECL, HCMOS options. Crystal resonators are preferred for: cost-sensitive designs, low-power applications, custom oscillator requirements, or when board space for oscillator circuit is available. XGHC offers both options to match your needs.

Choose oscillators for faster development and better stability. Choose resonators for cost savings and lower power.

What output types are available for XGHC crystal oscillators?

XGHC crystal oscillators offer various output types: (1) CMOS/HCMOS - most common, rail-to-rail square wave, compatible with digital logic

(2) LVCMOS - low-voltage CMOS for 1.8V/2.5V systems

(3) LVDS (Low Voltage Differential Signaling) - differential output for high-speed, low-noise applications

(4) LVPECL (Low Voltage Positive ECL) - differential output for high-frequency applications

(5) HCSL (High-Speed Current Steering Logic) - used for PCIe and high-speed serial

(6) Sine wave - analog output for RF applications. CMOS is most common and widely compatible. LVDS/LVPECL are for high-speed differential signaling. Choose based on your load requirements and signal integrity needs.

Choose CMOS for general applications. Choose LVDS/LVPECL for high-speed differential signaling.

What is the difference between TCXO and OCXO?

TCXO (Temperature Compensated Crystal Oscillator) and OCXO (Oven Controlled Crystal Oscillator) provide improved stability: TCXO uses electronic temperature compensation to achieve ±0.5-2.5ppm stability across temperature. It has faster warm-up, lower power consumption, and smaller size. OCXO uses a heated enclosure to maintain constant crystal temperature, achieving ±10-50ppb stability. It has longer warm-up (minutes), higher power consumption, and larger size. Choose TCXO for communication, GPS, and most precision applications. Choose OCXO for instrumentation, reference clocks, and highest precision timing. XGHC offers both types with various stability grades.

Choose TCXO for most precision applications. Choose OCXO for highest precision and reference applications.

How do I power and interface with crystal oscillators?

XGHC crystal oscillators are easy to interface: Power supply - connect VDD to specified voltage (1.8V, 2.5V, 3.3V, or 5V), bypass with 0.1μF and 10μF capacitors close to device. Ground - connect all GND pins to solid ground plane. Output - connect to clock input of your IC. Enable pin (if present) - tie high for normal operation or control for power saving. No external components needed for oscillation. Layout tips: keep power traces short, use adequate decoupling, avoid routing output near sensitive analog circuits. Oscillators are factory-tested and guaranteed to start reliably. XGHC oscillators include output enable/disable and sometimes standby modes.

Connect power, ground, and output. Add decoupling capacitors. No external oscillator circuit needed.
