1. Introduction
The PC404A facilitates evaluation of the TAOS analog linear sensor arrays (TSL201, TSL202,
TSL208, TSL1401, TSL1402, TSL1406, TSL1410, or TSL1301) by providing the necessary
timing and clock signals to support the on-board imaging device. The designer is then free to
investigate the properties and performance of the device without having to design and construct
support circuitry. A single 5 volt regulated power supply (and light) are the only inputs
required. An oscilloscope is required for observation and analysis of the output signals.
2. Functional Description
The linear sensor array support circuitry of the PC404A consists of an oscillator, a
counter/divider and logic to provide the imager with the required clock and integration pulse
signals for operation. The oscillator is built around a TLC555 timer. The oscillator output is
inverted and fed into divider U10 to provide lower frequency options. The clock frequency may
