Renesas’ Timing product portfolio has been acquired by SiTime.
Datasheets, documentation, and sample orders remain available on Renesas.com through late 2026. For new designs, purchasing, support, and product inquiries, visit SiTime.com or send an email to [email protected]. Full transition to SiTime is expected by late 2026.

The 853S54I-01 is a 2:1/1:2 Multiplexer. The 2:1 Multiplexer allows one of 2 inputs to be selected onto one output pin and the 1:2 MUX switches one input to one of two outputs. This device may be useful for multiplexing multi-rate Ethernet PHYs which have 100Mbit and 1000Mbit transmit/receive pairs onto an optical SFP module which has a single transmit/receive pair. A 3RD mode allows loop back testing and allows the output of a PHY transmit pair to be routed to the PHY input pair. For examples, please refer to the Application Block diagrams on pages 2-3 of the data sheet. The 853S54I-01 is optimized for applications requiring very high performance and has a maximum operating frequency in 2.5GHz. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards.
