ZHX2010 side-look fir transceiver ps007009-0302 1 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 localtalk tm and sharp ask tm modes, the transceiver combines an infrared emitting diode (ired) emitter, a pin photodiode detector, a programmable led driver, and a dif- ferential 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. features ? irda-data, sir, localtalk tm , and sharp ask tm ? data rates from 2400 bps?4 mbits/s ? ultracompact package: 9.8 mm long x 4.8 mm wide x 4.0 mm high ? on-chip led protection circuit ? supply voltage 2.7?5.25 v ? low power consumption: 2 ma at 2.7 v / 3 ma at 5.25 v (typical) ? ambient light and noise rejection circuitry ? power shutdown mode (~50 na typical) ? no external resistor required for led bias ? extended operating temperature range (?30 c to +85 c) ? meets iec 825-1 class 1 eye safety specifications

ZHX2010 side-look fir transceiver ps007009-0302 4 pin description table 1 lists the pin out for the fir transceiver. the pins are described in this sec- tion. v cc positive supply (power) connect to positive power supply (2.7?5.25 v). place a 0.33 f, 6 v, +/-20% ceramic bypass capacitor as close as possible to the v cc pin. gnd (power) connect to ground of the power supply. a solid ground plane is recommended for proper operation. tab (shield) the shield tab must be soldered to the ground plane. table 1. fir transceiver pin out pin name function i/o 1 leda ired anode ? 2 nc(ledc) do not connect ? 3 txd transmitter input i 4 rxd receiver output o 5 sd enables shutdown i 6v cc supply voltage ? 7 nc not connected ? 8 gnd ground ? ? tab shield ground ?
ZHX2010 side-look fir transceiver ps007009-0302 5 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) dur- ing 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 v cc . 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 fall- ing 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.
