The SY100E111JC is a phase-locked loop (PLL) clock buffer manufactured by Symmetry Electronics. It is designed to regulate the frequency of clocks and provide a clean signal for synchronization. The SY100E111JC is part of Symmetry Electronics\' Clock/Timing product line and is used in various applications that require precise timing. It is used in applications where an input signal is tapped, refined, and converted into a clean output signal. This allows for synchronization and high-precision timing for a variety of systems.

The SY100E111JC has an input frequency range of 0 MHz to 50 MHz and an output frequency range of 0 MHz to 300 MHz. It provides low jitter performance with a jitter specification of 0.8 ps RMS (12 kHz - 20 MHz). Additionally, it has a typical propagation delay of only 9 ns and a typical frequency multiplication factor of 7. The SY100E111JC has an operating temperature range of -40°C to 85°C and a 3.3 Vdc ±5% power supply.

The SY100E111JC is designed to be used in a variety of clock buffering applications such as Point-of-Load Power Supply, Digital TV Broadcasting, Networking Routers/Switches, FIFO systems and ATE systems. It is also used in various signaling synchronization applications such as SONET/SDH networks, data communications, and broadcast video systems. The SY100E111JC output can be used for multiplexing, clock distribution, fan-out, frequency shifting or multiplication applications.

The SY100E111JC utilizes a digitally controlled PLL (DPLL) circuit design to generate a stable output clock signal. It consists of a reference crystal oscillator, a programmable frequency divider, a phase frequency detector, and a voltage controlled oscillator. The frequency divider divides the input signal frequency and the phase frequency detector compares the divided signal with a reference clock. If the two signals are not in phase, a voltage signal is generated and is used to control the voltage controlled oscillator. This creates a feedback loop which ensures that the output clock is synchronized and has a precise frequency.

The SY100E111JC utilizes a patented artificial neuron adaptive control circuit to ensure a stable output clock frequency. This artificial neuron is a form of self-learning control system that uses its current output characteristics to drive its performance. This allows the SY100E111JC to quickly and continually adjust to changes in the environment, resulting in high performance and low jitter. It also reduces the need for manual tuning and increases overall system stability.

The SY100E111JC from Symmetry Electronics is a low jitter PLL clock buffer designed for precise timing applications. It has an input frequency range of 0 MHz to 50 MHz, an output frequency range of 0 MHz to 300 MHz and a low jitter performance of 0.8 ps RMS. It is suitable for a variety of clock buffering, signaling synchronization and frequency shifting applications. The SY100E111JC utilizes a digitally controlled DPLL circuit design and an artificial neuro adaptive control circuit to ensure a stable, precise output clock signal.
