The HSDL-3612 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-3612 can be completely shut down to achieve very low power consumption. In the shut down mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. The HSDL-3612 also incorporated 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-3612 front view options (HSDL-3612-007/-037) and a top view packaging option (HSDL-3612-008/-038) come with integrated shield that helps to ensure low EMI emission and high immunity to EMI field, thus enhancing reliable performance.
