The PL123S-09HSC is an advanced analog phase-locked clock synthesizer integrated circuit (IC) manufactured by Semtech. It features a low-noise, low-jitter output referenced to the external timing reference and consists of a phase tagger, a frequency divider, and a programmable frequency synthesizer (PLL). The PL123S-09HSC is designed for use in applications requiring a precise and stable clock and is suitable for use in communications, military, and avionics equipment.

The PL123S-09HSC features a phase tagger that locks to the rising edge of a periodic reference signal and generates a phase-locked loop (PLL) that contains a frequency synthesizer. This frequency synthesizer is based on a sigma-delta modulator, which uses a novel form of digital delta-sigma modulation to convert a periodic signal into a high-accuracy reference clock. The PL123S-09HSC also includes a low jitter divider and a clock output driver, which allows the synthesizer to generate a low jitter output clock.

The PL123S-09HSC is suitable for applications requiring precise frequency synthesis, such as communications and military equipment. The chip supports a wide range of frequency outputs and is capable of synthesizing up to six different frequencies, which makes it ideal for use in multi-channel systems. The chip’s output frequency selection is programmable and can be set by the user. The chip supports a wide range of output frequencies from 1 MHz to 127 MHz and provides a wide range of resolution to ensure precise frequency synthesis.

The PL123S-09HSC can also be used in applications requiring a highly accurate clock reference as it features an extremely low jitter output. This makes it suitable for applications such as high-speed communications interfaces, military equipment, and avionics. In addition, the chip offers an excellent power consumption to frequency output performance ratio, which makes it ideal for use in battery operated systems.

In summary, the PL123S-09HSC is an advanced analog phase-locked clock synthesizer IC that offers excellent performance and is suitable for applications requiring precise frequency synthesis or a highly accurate clock reference. With its programmability, low jitter output, and wide range of output frequencies, the PL123S-09HSC is an ideal choice for a wide range of applications.
