The PLL includes the FemtoClock® NG VCO along with the Pre-divider (P), the feedback divider (M) and the post divider (N). The P, M, and N dividers determine the output frequency based on the fXTAL reference. The feedback divider is fractional supporting a huge number of output frequencies. Internal registers are used to hold up the factory pre-set configuration setting. The P, M, and N frequency configurations support an output frequency range of 15.476MHz to 866.67MHz and 975MHz to 1,300MHz. An order code is assigned to each frequency configuration and the VCXO pull-range programmed by the factory (default frequencies). For more information on the available default frequencies and order codes, please see the Ordering Information Section in this document. For available order codes, see the FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information document. For more information on programming capabilities of the device for custom frequency and pull-range configurations, see the FemtoClock NG Ceramic 5x7 Module Programming Guide. The devices use the fractional feedback divider with a delta-sigma modulator for noise shaping and robust frequency synthesis capability. The relatively high reference frequency minimizes phase noise generated by frequency multiplication and allows more efficient shaping of noise by the delta-sigma modulator. The output frequency is determined by the 2-bit pre-divider (P), the feedback divider (M) and the 7-bit post divider (N). The feedback divider (M) consists of both a 7-bit integer portion (MINT) and an 18-bit fractional portion (MFRAC) and provides the means for high-resolution frequency generation. The output frequency fOUT is calculated by: 1 MFRAC + 0.5 f OUT = f XTAL  -------------  MINT + ------------------------------------PN 18 2 IDT8N3SV76CCD REVISION A NOVEMBER 19, 2013 3 ©2013 Integrated Device Technology, Inc. IDT8N3SV76 Data Sheet LVPECL-FREQUENCY PROGRAMMABLE VCXO Absolute Maximum Ratings NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.

Matched impedance techniques should be used to maximize operating frequency and minimize signal distortion. Figures 1A and 1B show two different layouts which are recommended only as guidelines. Other suitable clock layouts may exist and it would be recommended that the board designers simulate to guarantee compatibility across all printed circuit and clock component process variations. The clock layout topology shown below is a typical termination for LVPECL outputs. The two different layouts mentioned are recommended only as guidelines. The differential outputs are low impedance follower outputs that generate ECL/LVPECL compatible outputs.

This low-pass filter starts to attenuate noise at approximately 10 kHz. If a specific frequency noise component is known, such as switching power supplies frequencies, it is recommended that component values be adjusted and if required, additional filtering be added. Additionally, good general design practices for power plane voltage stability suggests adding bulk capacitance in the local area of all devices. Figure 3 shows an example of IDT8N3SV76 application schematic. In this example, the device is operated at VCC = 3.3V. As with any high speed analog circuitry, the power supply pins are vulnerable to random noise. To achieve optimum jitter performance, power supply isolation is required. In order to achieve the best possible filtering, it is recommended that the placement of the filter components be on the device side of the PCB as close to the power pins as possible. If space is limited, the 0.1µF capacitor in each power pin filter should be placed on the device side of the PCB and the other components can be placed on the opposite side. The schematic example focuses on functional connections and is not configuration specific. Refer to the pin description and functional tables in the datasheet to ensure that the logic control inputs are properly set. Power supply filter recommendations are a general guideline to be used for reducing external noise from coupling into the devices. The Figure 3.

Equations and example calculations are also provided. 1. Power Dissipation. The total power dissipation for the IDT8N3SV76 is the sum of the core power plus the power dissipated in the load(s). The following is the power dissipation for VCC = 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 = VCC_MAX * IEE_MAX = 3.465V * 157mA = 554.40mW • Power (outputs)MAX = 30mW/Loaded Output pair Total Power_MAX (3.3V, with all outputs switching) = 544.0mW + 30mW = 574.0mW 2. Junction Temperature. Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad directly affects the reliability of the device. The maximum recommended junction temperature is 125°C. Limiting the internal transistor junction temperature, Tj, to 125°C ensures that the bond wire and bond pad temperature remains below 125°C. The equation for Tj is as follows: Tj = JA * Pd_total + TA Tj = Junction Temperature JA = 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 JA must be used. Assuming no air flow and a multi-layer board, the appropriate value is 49.4°C/W per Table 6 below. Therefore, Tj for an ambient temperature of 85°C with all outputs switching is: 85°C + 0.574W * 49.4°C/W = 113.4°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 (multi-layer). Table 6.

Calculations and Equations. The purpose of this section is to calculate the power dissipation for the LVPECL output pair. LVPECL output driver circuit and termination are shown in Figure 4. VCC Q1 VOUT RL 50Ω VCC - 2V Figure 4. LVPECL Driver Circuit and Termination To calculate worst case power dissipation into the load, use the following equations which assume a 50 load, and a termination voltage of VCC – 2V. • For logic high, VOUT = VOH_MAX = VCC_MAX – 0.9V (VCC_MAX – VOH_MAX) = 0.9V • For logic low, VOUT = VOL_MAX = VCC_MAX – 1.7V (VCC_MAX – VOL_MAX) = 1.7V 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 – (VCC_MAX – 2V))/RL] * (VCC_MAX – VOH_MAX) = [(2V – (VCC_MAX – VOH_MAX))/RL] * (VCC_MAX – VOH_MAX) = [(2V – 0.9V)/50] * 0.9V = 19.8mW Pd_L = [(VOL_MAX – (VCC_MAX – 2V))/RL] * (VCC_MAX – VOL_MAX) = [(2V – (VCC_MAX – VOL_MAX))/RL] * (VCC_MAX – VOL_MAX) = [(2V – 1.7V)/50] * 1.7V = 10.2mW Total Power Dissipation per output pair = Pd_H + Pd_L = 30mW IDT8N3SV76CCD REVISION A NOVEMBER 19, 2013 14 ©2013 Integrated Device Technology, Inc. IDT8N3SV76 Data Sheet LVPECL-FREQUENCY PROGRAMMABLE VCXO Reliability Information Table 7. JA vs. Air Flow Table for a 6-lead Ceramic 5mm x 7mm Package JA vs. Air Flow Meters per Second Multi-Layer PCB, JEDEC Standard Test Boards 0 1 2 49.4°C/W 44.2°C/W 42.1°C/W Transistor Count The transistor count for IDT8N3SV76 is: 47,414 IDT8N3SV76CCD REVISION A NOVEMBER 19, 2013 15 ©2013 Integrated Device Technology, Inc. IDT8N3SV76 Data Sheet LVPECL-FREQUENCY PROGRAMMABLE VCXO Package Outline and Package Dimensions B D2 C F (TYP.)
