Output Enable (OEB) The Si5330 is a low-jitter, low-skew fanout buffer optimized for high-performance PCB clock distribution applications. The device produces four differential or eight single-ended, low-jitter output clocks from a single input clock. The input can accept either a single-ended or a differential clock allowing the device to function as a clock level translator. 3.1. VDD and VDDO Supplies The output enable (OEB) pin allows disabling or enabling of the outputs clocks (CLK0-CLK3). The output enable is logically controlled to ensure that no glitches or runt pulses are generated at the output as shown in Figure 3. IN CLKn The core VDD and output VDDO supplies have separate and independent supply pins allowing the core supply to operate at a different voltage than the I/O voltage levels. Disable OEB Disable Enable Enable Figure 3. OEB Glitchless Operation The VDD supply powers the core functions of the device, which operates from 1.8, 2.5, or 3.3 V. Using a lower supply voltage helps minimize the device’s power consumption. The VDDO supply pins are used to set the output signal levels and must be set at a voltage level compatible with the output signal format. All outputs are enabled when the OEB pin is connected to ground or below the VIL voltage for this pin. Connecting the OEB pin to VDD or above the VIH level will disable the outputs. Both VIL and VIH are specified in Table 5. All outputs are forced to a logic “low” when disabled. The OEB pin is 3.3 V tolerant. 3.2. Loss Of Signal Indicator (LOS) 3.4. Input Signals The input is monitored for a valid clock signal using an LOS circuit that monitors input clock edges and declares an LOS condition when signal edges are not detected over a 1 to 5 μs observation period. The LOS pin is asserted “low” when activity on the input clock pin is present. A “high” level on the LOS pin indicates a loss of signal (LOS). The LOS pin must be pulled to VDD as shown in Figure 2. The Si5330 can accept single-ended and differential input clocks. See “AN408: Termination Options for AnyFrequency, Any-Output Clock Generators and Clock Buffers—Si5338, Si5334, Si5330” for details on connecting a wide variety of signals to the Si5330 inputs. Si5330 The Si5330 supports single-ended output formats of CMOS, SSTL, and HSTL and differential formats of LVDS, LVPECL, and HCSL. It is normally required that the LVDS driver be dc-coupled to the 100 termination at the receiver end. If your application requires an accoupled 100 load, contact the applications team for advice. See AN408 for additional information on the terminations for these driver types. VDDO0 CLK0 VDDO1 CLK1 IN VDD LOS VDDO2 3.6. Input and Output Terminations CLK2 See AN408 for detailed information. 4.

All dimensions shown are in millimeters (mm) unless otherwise noted. Dimensioning and Tolerancing per ANSI Y14.5M-1994 specification. This Land Pattern Design is based on the IPC-7351 guidelines. Connect the center ground pad to a ground plane with no less than five vias to a ground plane that is no more than 20 mils below it. Via drill size should be no smaller than 10 mils. A longer distance to the ground plane is allowed if more vias are used to keep the inductance from increasing. Solder Mask Design 5. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the metal pad is to be 60 µm minimum, all the way around the pad. Stencil Design 6. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure good solder paste release. 7. The stencil thickness should be 0.125 mm (5 mils). 8. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pins. 9. A 2x2 array of 1.0 mm square openings on 1.25 mm pitch should be used for the center ground pad. Card Assembly 10. A No-Clean, Type-3 solder paste is recommended. 11. The recommended card reflow profile is per the JEDEC/IPC J-STD-020C specification for Small Body Components.
