The user side basically represents the functionalities that are visible to the end user. This side is responsible for “exchange of information” and “user interaction”. It usually consists of a TFT display with touch detection, NFC card readers for authentication or payments, and a Bluetooth interface for even more advanced features.
Oscillators for IEEE 1588 Protocol Applications
In general, the basic oscillator parameters for IEEE 1588 applications are:
- Standard frequency stability (Frequency, Temperature, Aging etc.)
- Phase noise and vibration (Jitter)
- Short and medium term stability (ADEV or MTIE/TDEV).
In IEEE 1588 applications with fewer synchronization requirements, standard Ethernet type XO with ±20ppm frequency stability is usually sufficient. However, IEEE 1588 applications with higher synchronization requirements, such as telecommunications, audio and video networks, need oscillators that meet certain short and medium term stability requirements.
The requirements for wired telecommunication network applications are defined by the following industry synchronization standards:
- Telcordia GR-1244, GR-253
- ITU-T G.812/G.813
- ITU-T G.8261/G.826
The requirements for wireless telecommunications applications are defined by the system requirements:
- LTE: Frequency accuracy is 50ppb, time accuracy is 3-10µs
- WiMAX: Frequency accuracy is 50ppb, time accuracy is 5-25µs
Audio and video applications must comply with IEEE 802.1AS-2011 standard.

Ultra-Low Vibration (Jitter) Oscillators
Fiber optic cables are one of the most important transmission lines used to transmit information in telecommunication networks. Information is transmitted by modulating the amplitude and phase of light using a technique called “coherent optical transmission”. Optical transceivers are used at both ends of the cable, allowing optical signals to be transmitted bidirectionally over the same fiber-optic cable. Optical transceivers make it possible for both a transmitter and a receiver to work together, creating a bidirectional (full duplex) connection.
The Digital Signal Processors (DSP) used in optical transceivers at both ends of the fiber optic connection offer increased transmission speeds of up to 800G, simpler circuit designs and improved optical performance. Digital Signal Handlers need clock oscillators, VCXOs and VCSOS with high frequency and ultra-low jitter as the reference frequency.
Raltron offers a complete range of oscillators that can be used as a compatible or reference design for the most leading optical DSPs used in optical transceivers.
Applications
