8N4Q001KG-1020CDI8

The 8N4Q001KG-1020CDI8 is a programmable timer and oscillator that features on-chip digital calibrated oscillator circuitry and clock processing, allowing users to obtain clock phase and frequency output in an adjustable combination. It is part of a family of digital clock and data recovery products, which repays its users with a set of features and options to meet their specific needs.

Applications using the 8N4Q001KG-1020CDI8 are diverse and include clock and data recovery, clock synthesis, clock jitter attenuation, Telecommunication networking, synchronous optical networking, wireless telecommunications networks, broadcast television/radio, image processing, High Performance Computing (HPC), military applications, and aerospace.

The working principle involves a differential balanced oscillator with integrated active loop filter (ALF). The ALF is a high-performance, digitally adjustable filter that allows the oscillator to utilize large frequency offsets and provide small ripples over a wide range of frequencies. This makes the 8N4Q001KG-1020CDI8 suitable for digitizing analog signals, as well as data communications links.

The 8N4Q001K is programmed through an on-board digital interface, allowing users to control the oscillator frequency, as well as the output phase and jitter. The oscillator\'s frequency resolution is programmable from 1 Hz per GHz (1.0e6 Hz/GHz)with up to a maximum frequency of 0.06 MHz. The output phase control can be adjusted from +/–30° relative to the input signal, as well as a differential output phase that can be programmed for-90 to +180°.

In terms of jitter performance, the 8N4Q001K is capable of up to 20 QUPS (Quality Units Per Second) in low jitter applications. It also includes an integrated PLL, allowing users to obtain stable jitter performance without the need for external components. Additionally, the phase-locked loop can generate a timing signal with a jitter tolerance of up to 0.5 UI (Unit Intervals).

In terms of power consumption, the 8N4Q001KG-1020CDI8 has an idle current of 4.5 mA, and a typical power consumption of 8 mA (3.3 V supply). The spread spectrum clock generation can be used to reduce the EMI radiation.

The 8N4Q001KG-1020CDI8 is an ideal choice for applications that require high performance and low power consumption in a small form factor. Its wide range of frequency, output phase control and jitter tolerance make it suitable for a variety of clock and data recovery applications.
