High-speed fibre-optic laser and receiver
The lasers and detectors division of Pacer Components has announced a new pair of 2.5Gbit fibre-optic components.
Available from UK opto specialist Pacer, the TSL2560 and TSL2561 transform light intensity into a digital signal output capable of direct I2C (TSL2561) or SMBus (TSL2560) interface.
From these outputs, a microcontroller can derive illuminance (ambient light level) in lux, using an empirical formula to approximate the human eye response.
Each convertor combines one broadband photodiode (visible plus infra-red) and one infrared-responding photodiode on a single CMOS IC capable of providing a near-photopic response over an effective 20bit dynamic range (16bit resolution).
No external circuitry is required for signal conditioning, and an interrupt feature is supported, improving system efficiency.
This approach is ideal for adapting display backlighting and keyboard illumination levels to changing ambient light conditions.
The new devices are also useful for general light sensing applications, exposure control in digital cameras, notebook/tablet PCs, street light control, security lighting, machine vision and automotive instrumentation. Request a free brochure from Pacer International ...
