2 / 20 page  2 Description The HSDL-3201 is one of a new generation of low-cost Infrared (IR) transceiver modules from Avago Technologies. It features the smallest footprint in the industry at 2.5 H x 8.0 W x 3.0 D mm. Although the supply voltage can range from 2.7 V to 3.6 V, the LED drive current is internally compensated to a constant 32 mA to assure that link distances meet the IrDA Data 1.4 (low power) physical layer specifications. The HSDL-3201 meets the 20 cm link distance to other IrDA 1.4 low power devices, and a 30 cm link distance to IrDA 1.4 standard devices. Application Circuit HSDL-3201#021 Pinout, Rear View VLED TXD 7 LED CURRENT SOURCE RXD 6 SHUT DOWN 5 RX PULSE SHAPER TXD 8 VLED 4 AGND SD RXD VCC 3 VCC 2 NC 1 GND C1 1.0 µF 87654321 HSDL-3201#008 Pinout, Rear View 87654321 Applications • Mobile telecom – Cellular phones – Pagers – Smart phones • Data communication – PDAs – Portable printers • Digital imaging – Digital cameras – Photo-imaging printers I/O Pins Configuration Table Pin Symbol Description Notes 1 GND Ground Connect to system ground. 2 NC No Connection This pin must be left unconnected. 3VCC Supply Voltage Regulated: 2.7 to 3.6 Volts 4 AGND Analog Ground Connect to a “quiet” ground. 5 SD Shut Down This pin must be driven either high or Active High low. Do NOT float the pin. 6 RXD Receiver Data Output is a low pulse for 2.4 μs Output. Active Low. when a light pulse is seen. 7 TXD Transmitter Data Logic high turns the LED on. If held Input. Active High. high longer than ~ 20 μs, the LED is turned off. TXD must be driven high or low. Do NOT float the pin. 8 VLED LED Voltage May be unregulated: 2.7 to 6.0 volts. - SHIELD EMI Shield Connect to system ground via a low inductance trace. For best performance, do not directly connect to GND or AGND at the part. |
