Design Note #57
OTEC was selected to develop a multi-channel data logging cockpit communications system. Supporting up to four microphones, two NTSC video channels, a variety of general purpose I/O with daylight visible LED enunciators was essential. Ruggedized circuit board design techniques were employed to make this compact piece of avionics gear flight-ready.
The Marvell PXA270 processor was selected as the main processing element. IIC bus mapped front panel indicators and controls make for a flexible user interface design. Add multiplexed audio codecs from Texas Instruments, USB Bus expanders from OKI and video decoding solutions from NXP to complete the feature-rich design.
With a trade-show in December, OTEC started the design of this five-circuit-board set in early October. Rapid electronic product development is OTEC’s hallmark and this PXA270-based data logger was no exception. Springing into high gear, OTEC’s development team delivered first hardware prototypes in under eight weeks. Demo software was running by week ten! The show was a success and our client booked pre-production orders.
