DESCRIPTION
74LVC1GX04
The 74LVC1GX04 is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 or 5 V devices. This feature allows the use of this device as translator in a mixed 3.3 and 5 V environment. This device is fully specified for partial power-down applications using Ioff at output Y. The Ioff circuitry disables the output Y, preventing the damaging backflow current through the device when it is powered down. The 74LVC1GX04 combines the functions of the 74LVC1GU04 and 74LVC1G04 to provide a device optimized for use in crystal oscillator applications. The integration of the two devices into the 74LVC1GX04 produces the benefits of a compact footprint, lower power dissipation and stable operation over a wide range of frequency and temperature.

APPLICATION INFORMATION Crystal controlled oscillator circuits are widely used in clock pulse generators because of their excellent frequency stability and wide operating frequency range. The use of the 74LVC1GX04 provides the additional advantages of low power dissipation, stable operation over a wide range of frequency and temperature and a very small footprint. This application information describes crystal characteristics, design and testing of crystal oscillator circuits based on the 74LVC1GX04. Crystal Characteristics Figure 8 is the equivalent circuit of a quartz crystal. The reactive and resistive component of the impedance of the crystal alone and the crystal with a series and a parallel capacitance is shown in Figure 9.

Figure 9 also shows that with a specified load capacitance (CL), the load resonance frequency (fL) is the same for a circuit with either a series (b) or parallel (c) capacitance. CL is specified by crystal manufacturers and is used in determining the value of the external components of the oscillator.

Design Figure 10 shows the recommended way to connect a crystal to the 74LVC1GX04. This circuit is basically a Pierce oscillator circuit in which the crystal is operating at its fundamental frequency and is tuned by the parallel load capacitance of C1 and C2. C1 and C2 are in series with the crystal. They should be approximately equal. R1 is the drive-limiting resistor and is set to approximately the same value as the reactance of C1 at the crystal frequency (R1 = XC1). This will result in an input to the crystal of 50% of the rail-to-rail output of X2. This keeps the drive level into the crystal within drive specifications (the designer should verify this). Overdriving the crystal can cause damage. The resistor Rf provides negative feedback and sets a bias point of the inverter near mid-supply, operating the 74LVC1GU04 in the high gain linear region. The value of Rf is not critical, typically it is set at 1 M. To calculate the values of C1 and C2, the designer can use C1 x C2 the formula: C L = ------------------- + C s C1 + C2 CL is the load capacitance as specified by the crystal manufacturer, Cs is the stray capacitance of the circuit (for the LVC1GX04 this is equal to an input capacitance of 5 pf). Testing
74LVC1GX04
After the calculations are performed for a particular crystal, the oscillator circuit should be tested. The following simple checks will verify the prototype design of a crystal controlled oscillator circuit. Perform them after laying out the board: * Test the oscillator over worst-case conditions (lowest supply voltage, worst-case crystal and highest operating temperature). Adding series and parallel resistors can simulate a worse case crystal. * Insure that the circuit does not oscillate without the crystal. * Check the frequency stability over a supply range greater than that which is likely to occur during normal operation. * Check that the start up time is within system requirements. As the 74LVC1GX04 isolates the system loading, once the design is optimized, the single layout may work in multiple applications for any given crystal.
