The SI5335D–B02840–GMR is a versatile programmable clock generator from Silicon Laboratories. It is a highly precise digital clock generator that enables users to reduce component count, save cost, and simplify the design of their systems. This device is designed for Network Timing, Processor Clock and Synchronization, and Medical instrumentation applications. The SI5335D–B02840–GMR offers precise control of output frequency and phase alignment, with on-chip programmable control registers and a I2C or SPI interface. This state-of-the-art device employs an on-chip, low-jitter voltage-controlled oscillator (VCO). In addition, the SI5335D–B02840–GMR has zero-delay-buffer (“ZDB”) functionality to deliver low-jitter operations with adjustable skew.

The SI5335D–B02840–GMR supports 10 differential LVDS/LVPECL outputs covering the frequency range from 20 kHz to 400 MHz. In addition, the device has been designed to save power since it offers a programmable sleep mode and features power down capability. It also offers a programmable spread spectrum capability that helps minimize conducted and radiated emissions. In addition to its digital/analog clock generator functionality, the SI5335D–B02840–GMR supports a variety of other features that make it highly desirable for network timing and medical instrumentation applications.

The working principle of the SI5335D–B02840–GMR is fairly straightforward. The device has an on-chip oscillator that can be programmed to run at any frequency from 20 kHz to 400 MHz. The oscillator frequency is then divided down by a series of programmable clock dividers and programmable Digital Lock Detect (DLD) dividers. The chosen output frequencies are then fed to the output buffers, which can be configured as LVDS or LVPECL. The device is also programmable to support spread spectrum operation, which helps to reduce EMI emissions and prevent EMI-induced jitter.

The SI5335D–B02840–GMR is ideal for processor clock, synchronization, and networking applications as it can provide precise and stable output frequencies with minimal jitter. The device is also highly configurable, so it can be programmed for any application-specific requirements. Due to its robust and advanced capabilities, the SI5335D–B02840–GMR is an excellent choice for mission-critical applications.
