SI5335D-B02231-GMR Clock/Timing – Clock Generators, PLLs, Frequency Synthesizers

The SI5335D-B02231-GMR belongs to the clock/timing portfolio of Silicon Labs, and is a high-performance clock and timing IC that functions as a clock generator or frequency synthesizer. The device provides excellent signal quality and low jitter performance in a single, low-cost, 3.2 mm x 3.2 mm, 32-lead package.

The SI5335D-B02231-GMR integrates a wide range of features and functions, including an external clock input, crystal oscillator, spread spectrum, jitter cleaner, clock mux, and an I²C-controlled phase-locked loop (PLL). The device is compatible with a variety of clock technologies, including LVDS, LVPECL, and HCSL, and can generate up to 16 different outputs ranging from 1MHz to 633MHz.

In addition to its clock/timing features, the SI5335D-B02231-GMR also provides excellent phase/frequency control features for improved signal integrity. The device provides the ability to adjust the input clock frequency, delay, and output clock frequency with a resolution of just 0.6ps. As a result, the device is well-suited for use in a variety of applications including telecommunications systems, clock distribution, industrial control systems, and embedded system.

The SI5335D-B02231-GMR functions through its dual-loop architecture, which includes a digitally-controlled oscillator (DCO) and a phase-locked loop (PLL). The DCO generates the master clock frequency, which is then fed into the PLL. The PLL locks onto the DCO’s signal and generates clock outputs that are in phase and frequency with the input signal. The clock outputs can be adjusted to a precise level using the I²C-controlled registers. The device also supports various modes of operation, including holdover mode and free-running mode. In addition, spread spectrum can be enabled for improved EMI performance.
