IR 3/16 Encode/Decode IC Technical Data HSDL-7001-2500 pc, tape and reel HSDL-7001#100-100pc, 50/tube Features - pliant with Ir DA 1.0 Physical Layer Specs - Interfaces with Ir DA 1.0 pliant IR Transceivers - Used in Conjunction with Standard 16550 UART - Transmits/Receives either 1.63 µs or 3/16 Pulse Mode - Internal or External Clock Modes - Programmable Baud Rate - 2.7-5.5 V Operation - 16 Pin SOIC Package Description The HSDL-7001 modulates and demodulates electrical pulses from Hewlett-Packard’s HSDL-1001 Infrared transceiver module and other Ir DA-pliant transceivers. The HSDL-7001 can be used with a microcontroller/ microprocessor that has a serial munication interface (UART). Prior to munication, the processor selects the transmission baud rate. Serial data is then transmitted or received at the prescribed data rate. The HSDL-7001 consists of two state machines - the SIR (Serial Infra Red) Encode and SIR Decode blocks. It also contains a sequential block Clock Divide which synthesizes the required internal signal. The HSDL-7001 can be placed into the Internal Clock Mode or External Clock Mode. An external crystal is needed for the Internal Clock Mode. In applications where the external 16XCLK signal is provided, a crystal is not needed. There are two data transmission modes. Data can be transmitted and received in either a standard 3/16 modulation mode or a 1.63 µs pulse mode.
