The MAX3109 advanced dual universal asynchronous receiver-transmitter (UART) has 128 words of receive and transmit first-in/first-out (FIFO) and a high-speed SPI or I²C controller interface. The 2x and 4x rate modes allow a maximum of 24Mbps data rates. A phase-locked loop (PLL) and the fractional baud-rate generators allow a high degree of flexibility in baud-rate programming and reference clock selection.Independent logic-level translation on the transceiver and controller interfaces allows ease of interfacing to microcontrollers, FPGAs, and transceivers that are powered by differing supply voltages. Automatic hardware and software flow control with selectable FIFO interrupt triggering offloads low-level activity from the host controller. Automatic half-duplex transceiver control with programmable setup and hold times allow the MAX3109 to be used in high-speed applications such as PROFIBUS-DP. The 128-word FIFOs have advanced FIFO control, reducing host processor data flow management.The MAX3109 is available in a 32-pin TQFN (5mm x 5mm) package, and is specified over the -40°C to +85°C extended temperature range.ApplicationsAutomotive Infotainment SystemsHandheld DevicesHVAC or Building ControlMedical SystemsPoint-of-Sales SystemsPower MetersProgrammable Logic Controllers (PLCs)

The MAX31180 is a low-jitter, crystal-based clock generator with an integrated phase-locked loop (PLL) to generate spread-spectrum clock outputs from 16MHz to 134MHz. The device is pin-programmable to select the clock multiplier rate as well as the dither magnitude. The MAX31180 has a spread-spectrum disable mode and a power-down mode to conserve power.ApplicationsAutomotiveCable ModemsCell PhonesComputer PeripheralsCopiersInfotainmentPCsPrinters

Maxim's MAX312/MAX313/MAX314 analog switches feature low on-resistance (10Ω max) and 1.5Ω on-resistance matching between channels. These switches conduct equally well in either direction. They offer low leakage over temperature (2.5nA at +85°C). Low power consumption and ESD tolerance greater than 2000V per Method 3015.7 are guaranteed.The MAX312/MAX313/MAX314 are quad, single-pole/single-throw (SPST) analog switches. The MAX312 is normally closed (NC), and the MAX313 is normally open (NO). The MAX314 has two NC switches and two NO switches. All three devices operate from a single supply of +4.5V to +30V or from dual supplies of ±4.5V to ±20V.ApplicationsAudio-Signal RoutingAvionicsCommunication SystemsData AcquisitionPBX/PABX SystemsSample-and-Hold CircuitsTest Equipment

The MAX3120 IrDA 1.2-compatible infrared transceiver is optimized for battery-powered, space-constrained applications. It consumes only 120µA while supporting data rates up to 115kbps over a wide 3V to 5.5V operating range, and features a 10nA shutdown mode to further extend battery life.The MAX3120 reduces the space required for IrDA applications by requiring a minimum of external components: photodiode, infrared LED, and current-setting resistor. Optical components are external to allow maximum flexibility in PC board design. The MAX3120 is available in 8-pin µMAX® and SO packages. The µMAX package consumes half the board space of an 8-pin SO.ApplicationsCell PhonesHandheld EquipmentIrDA ApplicationsPalmtop ComputersPDAs and Other Handheld DevicesPeripherals

Maxim's MAX312L/MAX313L/MAX314L analog switches feature low on-resistance (10Ω max) and 1.5Ω on-resistance matching between channels. These switches are +3V logic compatible when powered from ±15V or +12V supplies. The switches conduct equally well in either direction, and offer low leakage over temperature (2.5nA at +85°C).The MAX312L/MAX313L/MAX314L are quad, single-pole/single-throw (SPST) analog switches. The MAX312L is normally closed (NC), and the MAX313L is normally open (NO). The MAX314L has two NC switches and two NO switches. All three devices operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V, and are available in 16-pin TSSOP, SO, and DIP packages.ApplicationsAudio-Signal RoutingAvionicsCommunication SystemsData AcquisitionPBX/PABX SystemsSample-and-Hold CircuitsTest EquipmentXDSL Modems
