Description

3PEAK’s TPT4032 is an enhanced RS422 device which meets standard TIA/EIA -422-B with strong ESD protection capability. The BUS -pin can pass ±18kV HBM-ESD, and ±15 kV IEC -Air Charge ESD protection. It works in wide power supply range: from 3.0V to 5 .5V VCC, which design quad receiver for balanced communication. It also features the wide input common -mode voltage and higher data rate, the TPT4032 can accept -7V ~ +12V common-mode differential input with 100 Ω Load and 50Mbps data rate in 5.0V power supply, required by high speed field-bus applications. The TPT4032’s enable functions can control all four receivers and provide an active-high (G) or active-low (/G) enable input, and they provide the high - impedance state in the power -off condition, which only consume <1uA very low current. The TPT4032 is available in an SO P16 and TSSOP16 package, and is characterized from –40°C to 125°C. Typical Application Circuit

speed field-bus applications. The TPT4032 only consume <1uA very low current in the power-off condition. Figure 4. Function block diagram output is defined as certain state (typically high) through internal biasing circuits. of a transceiver from the bus. The TPT4032 has an internal circuit that ensures functionality during an idle bus.

A.2 TPT4032 High Speed Quad Differential RS422 Receiver Active-High in G and Active-Low in /G The G and /G logic inputs can configure the device to select receiver output status, and set a logic high on the G pin or a logic low on the /G pin to enable the device in normal operation mode, and it is easy to configure the logic from a controller or microprocessor. Power supply Both the logic and transmitters operate from a single power supply in wide range: 3.0 ~ 5.5V, making designs much more easily. The line quad drivers can operate off the same rail as the host controller or a similar low voltage supply, thus simplifying powe r structure. The 5.0V power supply is recommended to get better performance, especially in high data rate up-to 50Mbps.

Application Information

A typical system usually contain the drivers, receivers, and transceivers complied with RS -422, to reduce reflections in the transmission line, requires the proper cable termination for highly reliable applications. Only one driver on the bus is allowed per RS422 standard, as termination is used in circuit and it is usually placed at the end of the cable near the last receiver. In order to get the good performance and low cost of the application, and decide the type of termination. The different types of termination are unterminated lines, parallel termination, AC termination, and multipoint termination. For laboratory experiments, around 50 meter of 100-Ω, twisted-pair cable, a single driver and receiver, 3PEAK TPT4031 and TPT4032 were tested at room temper ature with in 5.0V supply voltage.
