HSDL-3208-S21

HSDL-3208-S21 Ultra Small Profile Package IrDA® Data Compliant Low Power 115.2 kbit/s Infrared Transceiver Data Sheet Description Features The HSDL-3208 is an ultra-small low cost infrared transceiver module that provides the interface between logic and infrared (IR) signals for through air, serial, half-duplex IR data link. The module is compliant to IrDA Physical Layer Specifications version 1.4 Low Power from 9.6 kbit/s to 115.2 kbit/s with extended link distance and it is IEC 825-Class 1 eye safe. • Fully compliant to IrDA 1.4 low power specification from 9.6 kbit/s to 115.2 kbit/s • Miniature package – Height: 1.60 mm – Width: 7.00 mm – Depth: 2.8 mm • Miniature package (with shield) – Height: 1.80 mm – Width: 7.4 mm – Depth: 2.90 mm • Guaranteed temperature performance, -25 to +70°C – Critical parameters are guaranteed over temperature and supply voltage • Low power consumption – Low shutdown current (1 nA typical) – Complete shutdown of TXD, RXD, and PIN diode • Withstands >100 mVp-p power supply ripple typically • Excellent EMI performance without shield • VCC supply 2.4 to 3.6 volts • LED stuck-high protection • Designed to accommodate light loss with cosmetic windows • IEC 825-class 1 eye safe The HSDL-3208 can be shut down completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. Such features are ideal for battery operated handheld products.

This pin can be connected directly to VCC (i.e. without series resistor) at less than 3 V. 2. Internally connected to the LED driver. 3. This pin is used to transmit serial data when SD pin is low. Do not float the pin. This pin has an internal 500 kΩ pulldown with a typical input capacitance of 2 pF. 4. This pin is capable of driving a standard CMOS or TTL load. No external pull-up or pull down resistor is required. It is in tri-state mode when the transceiver is in shutdown mode. This pin tristates with a weak 500 kΩ pullup resistor. 5. The transceiver is in shutdown mode if this pin is high. Do not float the pin. 6. Regulated, 2.4 to 3.6 volts. 7. Connect to system ground.
