C NOVEMBER 1, 2007 ICS8422002I-01 FEMTOCLOCKS™ CRYSTAL-TO-LVHSTL FREQUENCY SYNTHESIZER PRELIMINARY Application Information Power Supply Filtering Technique As in any high speed analog circuitry, the power supply pins are vulnerable to random noise. To achieve optimum jitter performance, power supply isolation is required. The ICS8422002I-01 provides separate power supplies to isolate any high switching noise from the outputs to the internal PLL. VDD, VDDA and VDDO should be individually connected to the power supply plane through vias, and 0.01µF bypass capacitors should be used for each pin. Figure 1 illustrates this for a generic VDD pin and also shows that VDDA requires that an additional 10Ω resistor along with a 10µF bypass capacitor be connected to the VDDA pin. 3.3V VDD .01µF 10Ω .01µF 10µF VDDA Figure 1. Power Supply Filtering Recommendations for Unused Input and Output Pins Inputs: Outputs: LVCMOS Control Pins LVHSTL Outputs All control pins have internal pull-ups or pull-downs; additional resistance is not required but can be added for additional protection. A 1kΩ resistor can be used. All unused LVHSTL outputs can be left floating. We recommend that there is no trace attached. Both sides of the differential output pair should either be left floating or terminated. Crystal INPUTS For applications not requiring the use of the crystal oscillator input, both XTAL_IN and XTAL_OUT can be left floating. Though not required, but for additional protection, a 1kΩ resistor can be tied from XTAL_IN to ground. REF_CLK INPUT For applications not requiring the use of the reference clock, it can be left floating. Though not required, but for additional protection, a 1kΩ resistor can be tied from the REF_CLK to ground. IDT™ / ICS™ LVHSTL FREQUENCY SYNTHESIZER 8 ICS8422002AGI-01 REV. C NOVEMBER 1, 2007 ICS8422002I-01 FEMTOCLOCKS™ CRYSTAL-TO-LVHSTL FREQUENCY SYNTHESIZER PRELIMINARY Crystal Input Interface The ICS8422002I-01 has been characterized with 18pF parallel resonant crystals. The capacitor values shown in Figure 2 below were determined using a 25MHz 18pF parallel resonant crystal and were chosen to minimize the ppm error. XTAL_IN C1 22p X1 18pF Parallel Crystal XTAL_OUT C2 22p Figure 2. Crystal Input Interface LVCMOS to XTAL Interface The XTAL_IN input can accept a single-ended LVCMOS signal through an AC coupling capacitor. A general interface diagram is shown in Figure 3. The XTAL_OUT pin can be left floating. The input edge rate can be as slow as 10ns. For LVCMOS inputs, it is recommended that the amplitude be reduced from full swing to half swing in order to prevent signal interference with the power rail and to reduce noise. This configuration requires that the output VDD impedance of the driver (Ro) plus the series resistance (Rs) equals the transmission line impedance. In addition, matched termination at the crystal input will attenuate the signal in half. This can be done in one of two ways. First, R1 and R2 in parallel should equal the transmission line impedance. For most 50Ω applications, R1 and R2 can be 100Ω. This can also be accomplished by removing R1 and making R2 50Ω.

In this example, the device is operated at VDD = 3.3V. Both input options are shown. The device can either be driven using a quartz crystal or a 3.3V LVCMOS signal. The C1= 22pF and C2 = 22pF are recommended for frequency accuracy. For different board layout, the C1 and C2 may be slightly adjusted for optimizing frequency accuracy. The LVHSTL output driver termination examples are shown in this schematic. The decoupling capacitor should be located as close as possible to the power pin. Figure 4.

C NOVEMBER 1, 2007 ICS8422002I-01 FEMTOCLOCKS™ CRYSTAL-TO-LVHSTL FREQUENCY SYNTHESIZER PRELIMINARY Power Considerations This section provides information on power dissipation and junction temperature for the ICS8422002I-01. Equations and example calculations are also provided. 1. Power Dissipation. The total power dissipation for the ICS8422002I-01 is the sum of the core power plus the power dissipated in the load(s). The following is the power dissipation for VDD = 3.3V + 5% = 3.465V, which gives worst case results. NOTE: Please refer to Section 3 for details on calculating power dissipated in the load. • Power (core)MAX = VDD_MAX * IDD_MAX = 3.465V * 100mA = 346.5mW • Power (outputs)MAX = 32.8mW/Loaded Output pair If all outputs are loaded, the total power is 2 x 32.8mW = 65.6mW Total Power_MAX (3.465V, with all outputs switching) = 346.5mW + 65.6mW = 412.1mW 2. Junction Temperature. Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad and directly affects the reliability of the device. The maximum recommended junction temperature for HiPerClockS devices is 125°C. The equation for Tj is as follows: Tj = θJA * Pd_total + TA Tj = Junction Temperature θJA = Junction-to-Ambient Thermal Resistance Pd_total = Total Device Power Dissipation (example calculation is in section 1 above) TA = Ambient Temperature In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance θJA must be used. Assuming a moderate air flow of 200 linear feet per minute and a multi-layer board, the appropriate value is 66.6°C/W per Table 6 below. Therefore, Tj for an ambient temperature of 85°C with all outputs switching is: 85°C + 0.412W * 66.6°C/W = 112.4°C. This is well below the limit of 125°C. This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow and the type of board (single layer or multi-layer). Table 6.

The purpose of this section is to derive the power dissipated into the load. LVHSTL output driver circuit and termination are shown in Figure 5. VDDO Q1 VOUT RL 50Ω Figure 5. LVHSTL Driver Circuit and Termination To calculate worst case power dissipation into the load, use the following equations which assume a 50Ω load. Pd_H is power dissipation when the output drives high. Pd_L is the power dissipation when the output drives low. Pd_H = (VOH_MAX /RL) * (VDDO_MAX - VOH_MAX) Pd_L = (VOL_MAX /RL) * (VDDO_MAX - VOL_MAX) Pd_H = (1.0V/50Ω) * (2V - 1.0V) = 20mW Pd_L = (0.4V/50Ω) * (2V - 0.4V) = 12.8mW Total Power Dissipation per output pair = Pd_H + Pd_L = 32.8mW IDT™ / ICS™ LVHSTL FREQUENCY SYNTHESIZER 12 ICS8422002AGI-01 REV.
