PI6LC48S04ZHIEX

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6LC48S04ZHIEX is a four-output clock synthesizer from Diodes Incorporated, designed for serial reference clock applications. It generates selectable output frequencies of 250MHz, 156.25MHz, 125MHz, or 100MHz from a 25MHz fundamental mode crystal. The device features two banks of differential outputs: two LVDS pairs and two low power HCSL pairs. It supports full 3.3V or 2.5V supply voltages and operates within an ambient temperature range of -40°C to 85°C. RMS phase jitter performance is specified at 0.21ps (typical) for the 1MHz–20MHz integration range and 0.32ps (typical) for the 12kHz–20MHz range at 156.25MHz. The component is housed in a 32-lead TQFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix ZHIEX confirms the tape and reel packaging format required for automated assembly processes. Ensure that the lead-free and green material specifications align with current environmental compliance standards for your manufacturing facility. Confirm that the 32-lead TQFN package dimensions match your printed circuit board land pattern design constraints before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a mix of LVDS and low power HCSL outputs is required from a single synthesizer source. Verify that the target application can accommodate the 25MHz crystal oscillator interface or utilizes the alternative REF_CLK pin if necessary. Ensure the system power budget supports the specified 3.3V or 2.5V operating voltages and that the thermal resistance characteristics fit the enclosure design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the HiFlex family of high-performance clock solutions from Diodes Incorporated. The HiFlex series focuses on providing versatile clocking options for complex digital systems. The PI6LC48S04 specifically addresses the need for mixed-signal output formats in a compact footprint, distinguishing it from standard single-format clock generators.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacement verification requires matching the 32-lead TQFN package and the specific combination of LVDS and HCSL outputs. Check datasheet compatibility for electrical parameters such as phase jitter and supply voltage ranges. Ensure that the frequency selection logic and pinout assignments are identical to avoid redesigning the host circuit board.
