Si533xx Low-Jitter, Fixed-Format Clock Buffers

Si533xx Low-Jitter, Fixed-Format Clock Buffers

Silicon Labs is significantly expanding the number of fixed-format LVPECL, LVDS, and LVCMOS clock buffers. The fixed-format buffers are recommended for clock distribution applications that need simple fanout buffers and users who are not willing to pay a premium for advanced features, such as clock output format selection and clock division. These buffers deliver more clock outputs and lower jitter than Silicon Labs’ legacy Si5330 fixed-format buffer family. These fixed-format buffers can be matched with Silicon Labs’ high performance clocks like Si5338/35/4x/8x and Si5xx XO/VCXOs, providing competitive clock tree solutions for any application.
