1. Describe

Skyworks' family of ultra-low power digital isolators are CMOS devices that offer significant data rate, propagation delay, power, size, reliability and external BOM advantages over traditional isolation technologies. Operating parameters of these products remain unchanged over a wide temperature range and throughout the life of the equipment, and feature ease of design and highly consistent performance characteristics. All device versions feature Schmitt Trigger inputs for high noise immunity and only require a VDD bypass capacitor. All devices support data rates up to 150 Mbps with propagation delays of less than 10 nanoseconds. The enable input provides a single-point control output drive for enabling and disabling.

7. Function Description

The Si8642BD-B-ISR channel operates like an optocoupler, except that the RF carrier is modulated instead of light. This simple architecture provides a strong isolated data path and requires no special consideration or initialization at startup. A channel consists of an RF transmitter and an RF receiver, separated by a semiconductor-based isolation barrier. Referring to the transmitter, input A uses on/off keying to modulate the carrier provided by the RF oscillator. The receiver contains a demodulator that decodes the input state according to its RF energy content and applies the result to output B via an output driver. This RF on/off keying scheme is superior to a pulse coding scheme because it offers best-in-class noise immunity, low power consumption and improved immunity to magnetic fields. For the data source, the tests used the Anritsu (MP1763C) Pulse pattern generator. The output of the generator clock and data from the Si8640 were captured on an oscilloscope set to 1.0 ns/div. This result shows that data integrity is maintained even at high data rates of 150 Mbps. The results also show 2 ns pulse width distortion and 350 ps peak jitter.
