ISPPAC-CLK5308S-01T48C is a fully integrated clock generator chip featuring an input multiplexer, an output buffer, and an integrated phase-locked loop (PLL). It is suitable for clock generation, jitter and clock frequency synthesis applications. The CLK5308S is a complete solution for ultra-low power, portable and board-level clock generation.

The ISPPAC-CLK5308S-01T48C provides selectable outputs with high frequency accuracy, which makes it suitable for use in applications requiring a stable clock signal. Clock output range is from 0.25 MHz to 50 MHz, with output drivers capable of driving both AC- and DC-coupled loads. The On-Chip Muxing Switch allows up to 8 output frequencies to be generated using the same input clock. The integrated PLL allows for frequency synthesis up to 400 MHz. The clock generator also supports programmable source enable/disable and delay.

The ISPPAC-CLK5308S-01T48C uses low-voltage differential signaling (LVDS) to transmit a clock signal. This ensures that the clock signal is immune to timing jitter, noise and electromagnetic interference. The device also supports configurable power-down and standby modes, to reduce power consumption when the device is not in use.

ISPPAC-CLK5308S-01T48C is suitable for a wide range of clock or timing applications, such as MPEG audio/video playback, digital video broadcasting, cellular baseband synchronization, digital multi-point video networks, wireless data networks, and ultrasound imaging. It is also suitable for use in home entertainment, printer, automotive and medical devices.

The ISPPAC-CLK5308S-01T48C features an integrated phase-locked loop (PLL), which is responsible for locking onto an input clock signal. The PLL utilizes a differentiator and a voltage-controlled oscillator (VCO) to convert the input clock signal into a high-frequency signal. The PLL has a programmable frequency range of 0.8MHz to 400MHz, as well as a wide range of output frequencies. It also features an adjustable multiplication factor (N), fEQ, and gain control.

This device also features an integrated output buffer. The output buffer is used to provide a reasonable output power level and reduce distortion by providing a local load for the PLL. It also serves to isolate the PLL from external loading. The buffer is separated from the PLL and each voltage domain has an independent low-noise power supply.

The ISPPAC-CLK5308S-01T48C also includes a selectable clock muxer with programmable input select and output enable. This allows for different frequency synthesis paths to be selected and routed to different destinations, making the device suitable for multiple clock distribution and frequency synchronization applications.

Overall, the ISPPAC-CLK5308S-01T48C is an excellent choice for clock generation, jitter and clock frequency synthesis applications due to its low-voltage differential signaling technology, wide range of programmable output frequencies and integrated output buffer. Its integrated phase-locked loop, selectable clock muxer and power-down modes make it more suitable than competing solutions for applications that require a stable clock signal and high frequency accuracy.
