HSDL-7001#100

Encoders, Decoders, Converters Overview

The HSDL-7001 is an IrDA SIR encoder/decoder IC designed to modulate and demodulate electrical pulses for infrared communication. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 115.2 kbps, utilizing a maximum clock frequency of 2 MHz on the 16XCLK input. The device interfaces with standard UARTs or microcontrollers via TXD and RCV pins. It features selectable internal or external clock modes, programmable baud rates via A0-A2 pins, and supports both 3/16 pulse modulation and 1.63 µs monoshot transmission modes. Packaged in a 16-pin SOIC.

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging configuration. The HSDL-7001#100 designation indicates a tube package containing 100 pieces per tube. Confirm that the required quantity aligns with this packaging format before finalizing procurement orders.

Encoders, Decoders, Converters Selection Notes

Select the HSDL-7001 when designing systems requiring IrDA 1.0 compliant serial infrared links. Ensure the host interface provides a 16XCLK signal derived from the UART baud rate if using external clock mode, or provide a crystal oscillator for internal clock mode. Verify that the application circuitry supports the 2.7 V to 5.5 V operating voltage range and accommodates the 16-pin SOIC package dimensions.

Encoders, Decoders, Converters Part Context

The HSDL-7001 functions as a dedicated interface between digital logic and infrared transceivers, such as the HSDL-1001. It translates UART serial data into modulated IR pulses for transmission and demodulates received IR signals back into serial data. This component enables wireless serial connectivity in portable electronics and peripherals without requiring complex protocol stacks at the base level.
