HSDL-1100 Functional
Description
Transmitter
The transmitter uses a high speed,high efficiency TS AlGaAs LED to produce an Ir signal of intensity and speed required by IrDA. The LED drive transistor is Schottky
clamped to aid in meeting the IrDA optical rise time, and pulse width specifications. The external components CX2 and R1 are recommended to obtain current peaking, which creates faster optical pulse edges. Fast optical edges will help the link meet the required IrDA power budget. LED current is set by selection of RLED. See the Transmitter Drive Requirements section.
