ZHX1820傳感器變送器的IrDA收發(fā)器模塊規(guī)格書PDF中文資料

ZHX1820屬于傳感器變送器的IrDA收發(fā)器模塊。由Zilog, Inc.制造生產(chǎn)的ZHX1820IrDA 收發(fā)器模塊紅外收發(fā)器在單個器件封裝中集成了紅外發(fā)射器、光電二極管和控制電路，用于數(shù)據(jù)傳輸，傳輸速率高達(dá) 16 Mbps。模塊有串行 (SIR)、中速 (MIR)、高速 (FIR) 三種版本，并提供側(cè)視或俯視兩種選項。紅外數(shù)據(jù)協(xié)會 (IrDa) 提供了用于無線數(shù)據(jù)通信的協(xié)議規(guī)范，例如配合紅外收發(fā)器使用的 IrDA 1.x 和 IrPHY 1.x。

Description

The ZILOG ZHX1820 is a low-profile version of ZiLOG’s popular ZHX1010 1-meter transceiver. Packaged in the “top-look” configuration (that is, the lens axis is perpendicular to the mounting surface), the transceiver is mechanically enhanced for ultra compact, power-conscious portable products, such as portable printers, handheld computers, and personal data assistants (PDAs). Designed to operate using the IrDA-Data mode, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN photodiode detector, a digital AC coupled LED driver, and a receiver/decoder in a single package.
