The SiT9376 is optimized for communications applications requiring low jitter and low power, and is available in the industry’s smallest differential package.
This differential oscillator supports any frequency between 1 MHz and 220 MHz. It features 150 fs RMS jitter (typ.), excellent immunity to power supply noise and environmental hazards, industry-standard package sizes down to 2.0 x 1.6 mm, low-power options, and wide temperature support up to 105°C.
The SiT9376 offers popular output drivers for LVPECL, LVDS, HCSL, and low-power HCSL with integrated termination resistors. It also features a unique FlexSwing™ driver that performs like LVPECL but with independent control of VOH and VOL levels to simplify interfacing with chipsets having non-standard input-voltage requirements. The SiT9376 accepts power-supply voltages down to 1.8V for additional power savings.
