ZHX2010 Side-Look FIR Transceiver

Description
The ZiLOG ZHX2010 is an ideal side-look transceiver for applications in today's ultracompact power-conscious portable products, such as notebook PCs, mobile phones, digital cameras, portable printers, handheld computers, or personal data assistants (PDAs). Designed to support all IrDA at up to 4 Mb/s and LocalTalkTM and Sharp ASKTM modes, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN photodiode detector, a programmable LED driver, and a differential receiver in a single, miniature package. The ZiLOG ZHX2010 provides an efficient implementation of the IrDA-Data 1.4 standard in a small footprint format. Application circuit space is also minimized, as only two external components (a terminating resistor and a decoupling capacitor) are required to implement a complete IrDA transceiver solution. The ZHX2010 is capable of legacy-mode power management and bandwidth switching.

TXD Transmit Data
(Input, active high) This CMOS input is used to transmit serial data when SD is low. An on-chip protection circuit disables the IRED driver if the TX pin is asserted for longer than 100 s. When used in conjunction with the SD pin, this pin also provides control signals to the internal digital serial control interface and legacy mode subsystems. This input has an internal pull-down resistor that is disabled (open-circuited) during shutdown. TXD has integrated digital AC coupling that prevents inadvertent "always on" IREDs; therefore, no external AC coupling components are required for input signals between GND and VCC.
RXD Receive Data
(Output, active low) This output indicates received serial data. It is a push-pull CMOS driver capable of driving a standard CMOS or TTL load. No external pull-up or pull-down resistor is required.
SD Shutdown
(Input, active high) This CMOS input pad functions as a shutdown switch and as a mode switch, allowing bandwidth changes. Shutdown and Legacy Mode Bandwidth Switching Assertion of this pin high for a period of time exceeding 500 m places the module into legacy shutdown mode, reducing current consumption to ~50 nA. On the falling edge of this signal, the state of the TX pin is sampled and used to set receiver low bandwidth (TX = Low) or high bandwidth (TX = High) mode. The transceiver powers on with the upper limit of the receiver bandwidth set to 1.152 Mbits/s operation. To set the bandwidth for operation at 4 Mbits/s, apply the timings shown in Figure 3 to the SD and the TX inputs.

Note: The internal LED driver is disabled when SD is active and is not enabled until the next rising edge of TX. This ensures that the LED is not active during bandwidth adjustment. It is recommended that the SD pin be connected to GND if the bandwidth adjustment and shutdown modes are not required.
