RC19202AGNT#BD0

Overview

The RC19202AGNT#BD0 is a PCIe Gen7 compliant 2:2 clock multiplexer from the Renesas RC192xx family. It operates with a core voltage of 3.3V and supports input frequencies from 1 MHz to 400 MHz. The device accepts LVDS or HCSL differential inputs and provides two LP-HCSL differential outputs. Key electrical specifications include an additive phase jitter of 37 fs RMS typical and a noise floor of -154 dBc/Hz. It features a propagation delay maximum of 1.7 ns and functions within a temperature range of -40°C to +105°C.

Feature Summary

• PCIe Gen7 compliance with backward compatibility for Gen1 through Gen6
• Ultra-low additive phase jitter (37 fs RMS typ) and noise floor (-154 dBc/Hz)
• Flexible power sequencing, automatic clock parking, and loss-of-signal indicator
• SMBus write protection with support for multiple addresses

Applications

• High-speed serial interconnect systems requiring low-jitter clock distribution
• PCI Express infrastructure supporting Gen1 through Gen7 standards
• Server and storage backplane clocking solutions

Procurement Notes

Verify the package type against official datasheets, as local listings may contain conflicting descriptions such as TSSOP. Confirm the specific ordering suffix BD0 corresponds to the VFQFPN-20 tray packaging format. Ensure the component meets the required RoHS compliance and lead-free status before integration into production designs.

Selection Notes

Select this component when a 2:2 multiplexing function is required for PCIe applications up to Gen7 speeds. The 3.3V supply requirement distinguishes it from lower-voltage alternatives like the RC193 series. Verify that the LP-HCSL output signaling matches the load requirements of the destination devices in the system architecture.

Part Context

This part belongs to the RC192xx family of high-performance clock multiplexers designed for PCI Express compliance. It shares architectural similarities with other members like the RC19216 but offers a 2:2 ratio instead of 2:16. The device is manufactured by Renesas Electronics and is intended for robust design margins in high-speed data transmission environments.

Replacement Considerations

Direct substitutes within the same family include the RC19202A variants with different packaging suffixes. For broader compatibility, verify if the RC19302A00AGNT#BD0 can be used if the system supports 1.8V operation.
