8SLVD1204-33NLGI/W

Clock Buffers, Drivers Overview

The 8SLVD1204-33NLGI/W is a high-performance differential LVPECL fanout buffer manufactured by Renesas Electronics Corporation. It supports PCI Express Gen 1 through Gen 5 standards and features four low-skew, low additive jitter LVPECL output pairs alongside two selectable differential clock input pairs. The device accommodates various differential input levels including LVDS, LVPECL, and CML, with a maximum input clock frequency of 2GHz. Key electrical parameters include an output skew of 5ps (typical), a propagation delay of 320ps (maximum), and a maximum RMS additive phase jitter of 40fs at 156.25MHz. It operates on full 3.3V or 2.5V supply voltages with a maximum current consumption of 60mA.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix '33NLGI/W' against official Renesas documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with 3.3V or 2.5V supply requirements. Check for RoHS 6 compliance and confirm the 16-VFQFPN package dimensions match design constraints. Validate operating temperature range of -40°C to 85°C for the intended environment.

Clock Buffers, Drivers Selection Notes

Select this component when low additive phase noise and precise skew characteristics are critical for high-speed serial links. The 8SLVD1204 is suitable for applications demanding repeatability in clock distribution. Consider the 2GHz maximum frequency limit and 60mA current consumption. Ensure the system can accommodate the 16-VFQFPN package size and that the control input interface aligns with LVCMOS levels.

Clock Buffers, Drivers Part Context

The 8SLVD1204 belongs to Renesas' FemtoClock family of high-performance clock buffers. This series is designed for fanoutting high-frequency, very-low additive phase-noise clock and data signals. The device guarantees output-to-output and part-to-part skew characteristics, making it ideal for applications requiring well-defined performance. It integrates bias voltage references to facilitate single-ended signal interfacing.

Clock Buffers, Drivers Replacement Considerations

The 8SLVP1204 is a related variant within the same product family offering similar LVPECL fanout capabilities. Verify pinout compatibility and electrical parameter equivalence before substitution. Confirm that the replacement part meets the specific PCIe generation support and jitter requirements of the original design.
