8538BG-31LF Description

Short technical summary and product information.

The 8538BG-31LF is a clock fanout buffer and multiplexer IC manufactured by Renesas. It provides a single circuit with a 2:8 input-to-output ratio, allowing one of two input sources to be distributed to eight outputs. The device accepts LVCMOS, LVTTL, or crystal inputs and delivers LVPECL differential outputs.

 

Operating from a 3.135V to 3.465V supply, the 8538BG-31LF supports a maximum output frequency of 266 MHz. The differential outputs help reduce noise and improve signal integrity in high-speed clock distribution applications. The device is specified for the commercial temperature range of 0°C to 70°C.

 

Housed in a surface-mount 28-TSSOP package (0.173", 4.40mm width), the 8538BG-31LF is suitable for compact PCB layouts. The 2:8 fanout architecture makes it ideal for clock tree buffering, frequency synthesis, and general-purpose clock distribution in digital systems.
