ZT230E Storage Considerations
Storage in a low humidity environment is preferred. Large high density plastic packages are moisture sensitive and should be stored in Dry Vapor Barrier Bags. Prior to usage, the parts should remain bagged and stored below 40C and 60%RH. If the parts are removed from the bag, they should be used within 48 hours or stored in an environment at or below 20%RH. If the above conditions cannot be followed, the parts should be baked for four hours at 125C in order remove moisture prior to soldering. Zywyn ships product in Dry Vapor Barrier Bags with a humidity indicator card and desiccant pack. The humidity indicator should be below 30%RH.

Zywyn Corporation Circuit Description
Proprietary Switch-Capacitor Regulated Voltage Converter
Different from other suppliers, Zywyn uses a patent pending switch-capacitor voltage-controlled source and sink current generators design to provide powerful bipolar voltages to maintain compliant EIA/RS232 levels regardless of power supply fluctuations. The design consists of an internal regulated oscillator, a two phase clock cycling, regulated complementary MOS switches, fast switching diode and switch capacitors. The switch capacitor bi-directional current generators operate with Zywyn's proprietary smartly regulated complementary MOS switches and fast switching diode from its proprietary high voltage process technology. The efficiency of these bidirectional www..com current generators is well over 70%. The switching frequency is generated by an internal oscillator and regulated by the current loads. The switch capacitor pump design delivers higher negative bucked voltage than the positive boosted voltage to achieve a balanced voltage controlled source and sink current generators resulting a balanced bipolar voltage supplies to the chip. With its unique proprietary design technique, Zywyn's interface product series provide a better power efficient, stable and compliant EIA/RS232 levels with superior low power consumption.
ZT230E
ESD Immunity
Electro-Static Discharge (ESD) is an important factor when implementing a serial port into a system. In some applications, it is crucial that the ESD protection for the system must meet a certain tolerance level. Since RS232 transceiver devices are exposed to the outside world, there are many environmental factors that can effect the serial port and even subject it to transients that could potentially damage the transceiver itself. The RS232 transceiver is usually routed from the serial port connector to the transceiver IC through the metal trace on the printed circuit board. This trace will have some small amount of resistance that will add some protection in terms of limiting transient current to the IC. However for added voltage protection, transient voltage suppressors (TVS) or transzorbs, which are back-to-back diode arrays clamp, are usually necessary to protect the serial port circuity. To further reduce cost within their system, more engineers are requiring higher ESD tolerances from the transceiver ICs themselves without having to add costly TVS circuitry. Zywyn's RS232 transceivers includes built-in transient voltage suppression where external ESD circuitry is not necessary to meet the MIL-STD-883, Method 3015, Human Body Model and the EN61000-4-2 Air/Contact Discharge tests. The Human Body Model has been the generally accepted ESD testing method for semiconductors. This test is intended to simulate the human body's potential to store electrostatic energy and discharge it to an integrated circuit upon close proximity or contact. This method will test the IC's capability to withstand an ESD transient during normal handling such as in manufacturing areas where the ICs tend to be handled frequently.
Controlled Enable and Power-Down
The ZT211E and ZT213E both feature an enable input, which allows the receiver outputs to be either tri-stated or enabled. This can be especially useful when the receiver is tied directly to a microprocessor data bus. For the ZT211E, enable is active low, in which a logic LOW applied to the EN pin will enable the receiver outputs. For the ZT213E, enable is active high in which a logic HIGH applied to the EN pin will enable the receiver outputs. ZT211E and ZT213E have a low-power shutdown mode controlled by the SD pin. During shutdown the driver output and the switch-capacitor regulated voltage converter are disabled with the supply current falls to less than 1A. ZT213E includes a wakeup function (see Table 1) that enables two receivers during a shutdown state. With only the receivers active during the shutdown state, the devices draw 5-10A of supply current. A typical application is when a RS232 cable is connected or when the peripheral is enabled such as a modem, the devices will automatically become active again. The ring indicator signal from the modem could be passed through an active receiver in the ZT213E that is itself in the shutdown mode. The ring indicator signal would propagate through the ZT213E to the power management circuitry of the computer to power up the microprocessor and the ZT213E drivers. After the supply voltage to the ZT213E reaches +5.0V, the SD pin can be disabled, taking the ZT213E out of the shutdown mode. All receivers that are active during shutdown maintain 500mV (typ.) of hysteresis.

RS232 Signal Characteristics
The charge pump voltage converter efficiently converts the necessary voltage for the driver's output transistors so that the RS232 output is close to the ideal rail voltage of 10V. While loaded with a typical RS232 load, the driver's output level only drops 0.2V from its open circuit voltage. Zywyn's low-drop driver circuitry working with its efficient voltage regulator allows superior line driving capability while meeting the requirements of TIA/EIA-232-E. The drivers are inverting transmitters, which accept TTL or CMOS inputs and produces the RS-232 compliant signals that is inverted relative to the input logic levels. Typically the RS232 output voltage swing is 6V. Even under the worst case loading www..comconditions of 3kohms and 2500pF, the output is guaranteed to be 5V, which adheres to the RS232 standard specifications. The transmitter outputs are protected against infinite short-circuits to ground without degradation in reliability. The instantaneous slew rate of the transmitter output is internally limited to a maximum of 30V/s in order to meet the TIA/EIA-232-E requirements.
ZT230E
The receivers convert RS-232 input signals to inverted TTL signals. The inputs have a typical hysteresis margin of 500mV in order to account for signal degradation caused by system interference and other noise related disturbers. This ensures that the receiver is relatively immune to noisy transmission lines. The input thresholds are 0.8V minimum and 2.4V maximum, which are within the TIA/EIA-232 requirements. The receiver inputs are also protected against voltages up to 25V. Should an input be left unconnected, a 5kohm pulldown resistor to ground will force the output of the receiver to a high state.

Test Circuit RS232 Signal Characteristics
Figure 1 shows the normal RS232 transceiver function with a TTL/CMOS signal applied to the input on channel 1 and the resultant RS232 output shown on channel 2. This figure shows a typical RS232 line driver output without loading. In other words, this is the open circuit RS232 output voltage. The charge pump voltage converter efficiently converts the necessary voltage for the driver's output transistors so that the RS232 output is close to the ideal rail voltage of 6.6V. Figure 2 shows the RS232 transceiver function using the TTL/CMOS input on channel 1 while showing the RS232 output on channel 2. This figure shows the RS232 signal while the output is loaded with 3kohms and 1000pF. The resistive load is the receiver's input impedance as the driver's output is looped back to the receiver's input. The resultant output on channel 3 is the receiver's TTL/CMOS output. While loaded with a typical RS232 load, the driver's output level only drops 0.2V from its open circuit voltage while running at 250kbps. The RS-232 output on channel 2 also shows good signal integrity while at the high data rates, which allows the receiver to process the signal will minimum skew and delay. Zywyn's low-drop driver circuitry working with its efficient voltage regulator allows superior line driving capability with the bonus of 15kV ESD immunity.
