HSDL-3602 Functional block diagram
The HSDL-3602 contains a highspeed and high-efficiency 870 nm LED, a silicon PIN diode, and an integrated circuit. The IC contains an LED driver and a receiver providing a single output (RXD) for all data rates supported. The HSDL-3602 can be completely shut down to achieve very low power consumption. In the shut down mode, the PIN diode is inactive, thus producing very
little photo-current even under very bright ambient light. The HSDL-3602 also incorporates the capability for adjustable optical power. With two programming pins; MODE 0 and MODE 1, the optical power output can be adjusted lower when the nominal desired link distance is one-third or two-third of the full IrDA link. The HSDL-3602 comes with a front view packaging option (HSDL-3602-007/-017). It has an
integrated shield that helps to ensure low EMI emission and high immunity to EMI field, thus enhancing reliable performance.

The condition is maintained for duration dependent on the pattern and strength of the incident intensity. 4. To maintain low shutdown current, TXD needs to be driven high or low and not left floating.
Recommended Application Circuit Components Component Recommended Value R1 2.2 ± 5%, 0.5 Watt, for 2.7 VCC 3.3 V operation 2.7 ± 5%, 0.5 Watt, for 3.0 VCC 3.6 V operation CX1[5] 0.47 ”F ± 20%, X7R Ceramic [6] CX2 6.8 ”F ± 20%, Tantalum
Notes: 5. CX1 must be placed within 0.7 cm of the HSDL-3602 to obtain optimum noise immunity. 6. In "HSDL-3602 Functional Block Diagram" on page 3 it is assumed that Vled and VCC share the same supply voltage and filter capacitors. In case the 2 pins are powered by different supplies CX2 is applicable for Vled and CX1 for VCC. In environments with noisy power supplies, including CX2 on the V CC line can enhance supply rejection performance.
