GTL2002 2-bit bidirectional low voltage translator Rev. 8 — 19 August 2013 Product data sheet 1. General description The Gunning Transceiver Logic - Transceiver Voltage Clamps (GTL-TVC) provide high-speed voltage translation with low ON-state resistance and minimal propagation delay. The GTL2002 provides 2 NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference transistor (SREF and DREF). The device allows bidirectional voltage translations between 1.0 V and 5.0 V without use of a direction pin. When the Sn or Dn port is LOW the clamp is in the ON-state and a low resistance connection exists between the Sn and Dn ports. Assuming the higher voltage is on the Dn port, when the Dn port is HIGH, the voltage on the Sn port is limited to the voltage set by the reference transistor (SREF). When the Sn port is HIGH, the Dn port is pulled to VCC by the pull-up resistors. This functionality allows a seamless translation between higher and lower voltages selected by the user, without the need for directional control. All transistors have the same electrical characteristics and there is minimal deviation from one output to another in voltage or propagation delay. This is a benefit over discrete transistor voltage translation solutions, since the fabrication of the transistors is symmetrical. Because all transistors in the device are identical, SREF and DREF can be located on any of the other two matched Sn/Dn transistors, allowing for easier board layout. The translator's transistors provide excellent ESD protection to lower voltage devices and at the same time protect less ESD-resistant devices. 2.

Application design-in information 8.1 Bidirectional translation For the bidirectional clamping configuration, higher voltage to lower voltage or lower voltage to higher voltage, the GREF input must be connected to DREF and both pins pulled to HIGH side VCC through a pull-up resistor (typically 200 k). A filter capacitor on DREF is recommended. The processor output can be totem pole or open-drain (pull-up resistors may be required) and the chip set output can be totem pole or open-drain (pull-up resistors are required to pull the Dn outputs to VCC). However, if either output is totem pole, data must be unidirectional or the outputs must be 3-stateable and the outputs must be controlled by some direction control mechanism to prevent HIGH-to-LOW contentions in either direction. If both outputs are open-drain, no direction control is needed. The opposite side of the reference transistor (SREF) is connected to the processor core power supply voltage. When DREF is connected through a 200 k resistor to a 3.3 V to 5.5 V VCC supply and SREF is set between 1.0 V to (VCC  1.5 V), the output of each Sn has a maximum output voltage equal to SREF and the output of each Dn has a maximum output voltage equal to VCC. 1.8 V 1.5 V 1.2 V 1.0 V 5V 200 kΩ totem pole or open-drain I/O VCORE GND GREF SREF DREF S1 D1 S2 D2 CPU I/O VCC CHIPSET I/O increase bit size by using 10-bit GTL2010 or 22-bit GTL2000 3.3 V VCC S3 D3 S4 D4 S5 D5 Sn Dn CHIPSET I/O 002aac060 Typical bidirectional voltage translation.

All rights reserved. 5 of 27 GTL2002 NXP Semiconductors 2-bit bidirectional low voltage translator 8.2 Unidirectional down translation For unidirectional clamping, higher voltage to lower voltage, the GREF input must be connected to DREF and both pins pulled to the higher side VCC through a pull-up resistor (typically 200 k). A filter capacitor on DREF is recommended. Pull-up resistors are required if the chip set I/O are open-drain. The opposite side of the reference transistor (SREF) is connected to the processor core supply voltage. When DREF is connected through a 200 k resistor to a 3.3 V to 5.5 V VCC supply and SREF is set between 1.0 V to (VCC  1.5 V), the output of each Sn has a maximum output voltage equal to SREF. 1.8 V 1.5 V 1.2 V 1.0 V 0.8 V easy migration to lower voltage as processor geometry shrinks VCORE CPU I/O 5V 200 kΩ GTL2003 GND GREF SREF DREF S1 D1 S2 D2 VDD1 CHIPSET I/O totem pole I/O S8 D8 002aac061 Typical unidirectional HIGH-to-LOW voltage translation. Fig 7. Unidirectional down translation to protect low voltage processor pins 8.3 Unidirectional up translation For unidirectional up translation, lower voltage to higher voltage, the reference transistor is connected the same as for a down translation. A pull-up resistor is required on the higher voltage side (Dn or Sn) to get the full HIGH level, since the GTL-TVC device will only pass the reference source (SREF) voltage as a HIGH when doing an up translation. The driver on the lower voltage side only needs pull-up resistors if it is open-drain. 1.8 V 1.5 V 1.2 V 1.0 V 0.8 V easy migration to lower voltage as processor geometry shrinks VCORE CPU I/O totem pole I/O or open-drain 5V 200 kΩ GTL2003 GND GREF SREF DREF S1 D1 S2 D2 S8 D8 VDD1 CHIPSET I/O 002aac062 Typical unidirectional LOW-to-HIGH voltage translation.

All rights reserved. 6 of 27 GTL2002 NXP Semiconductors 2-bit bidirectional low voltage translator 8.4 Sizing pull-up resistor The pull-up resistor value needs to limit the current through the pass transistor when it is in the ON state to about 15 mA. This will guarantee a pass voltage of 260 mV to 350 mV. If the current through the pass transistor is higher than 15 mA, the pass voltage will also be higher in the ON state. To set the current through each pass transistor at 15 mA, the pull-up resistor value is calculated as shown in Equation 1: pull-up voltage  V  – 0.35 V resistor value    = -------------------------------------------------------------------------0.015 A (1) Table 6 summarizes resistor values for various reference voltages and currents at 15 mA and also at 10 mA and 3 mA. The resistor value shown in the +10 % column or a larger value should be used to ensure that the pass voltage of the transistor would be 350 mV or less. The external driver must be able to sink the total current from the resistors on both sides of the GTL-TVC device at 0.175 V, although the 15 mA only applies to current flowing through the GTL-TVC device.

A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 15.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 15.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • • • • • • Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 15.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities GTL2002 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 17 of 27 GTL2002 NXP Semiconductors 2-bit bidirectional low voltage translator 15.4 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 17) than a SnPb process, thus reducing the process window • Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 13 and 14 Table 13. SnPb eutectic process (from J-STD-020D) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350  350 < 2.5 235 220  2.5 220 220 Table 14.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 17.
