545BCA837M500CCG

The Skyworks Solutions 545BCA837M500CCG is a crystal oscillator (XO) from the Ultra Series Si545 family, providing a 837.5 MHz LVDS output clock. It utilizes DSPLL technology to achieve ultra-low jitter of 80 fs typical (12 kHz – 20 MHz) and excellent power supply noise rejection of –80 dBc typical. The device is factory-programmable to any frequency from 0.2 to 1500 MHz, supporting multiple output formats including LVDS, LVPECL, CML, HCSL, and CMOS. This specific configuration is fixed at 837.5 MHz with LVDS output.

The oscillator offers ±7 ppm frequency stability over the industrial temperature range of -40°C to 85°C. It operates from a single supply voltage that can be 1.8V, 2.5V, or 3.3V, simplifying power supply design. The supply current is typically 121 mA. The enable/disable function allows power-down control.

The device is housed in a compact 6-SMD, no lead package measuring 3.20 mm x 2.50 mm x 1.00 mm, suitable for surface mount assembly. It is also available in alternative package sizes (2.5x3.2, 3.2x5, 5x7 mm) for design flexibility. The Si545 family is designed for high-performance timing applications requiring low jitter and frequency flexibility, such as 100G/200G/400G networking equipment.
