ABMJB-902-Q74USY-T3 Datasheet/PDFThe ABMJB-902-Q74USY-T3 is a critical component in many applications, such as frequency-agile radios, communication networks, and distributed systems.
Application field
The ABMJB-902-Q74USY-T3 is a Clock Generator, PLL, or Frequency Synthesizer built to produce multiple clock and timing signals from a single reference frequency. It is mainly used in telecommunication systems, data processing systems, military systems, and entertainment electronics that require a wide range of clock and timing signals. The device\'s multiple outputs are completely independent of each other, and can be configured to generate a wide range of frequencies and voltage levels. It can also generate high-quality clock signals with very low jitter and minimal thermal drift.
Working principle
The unit utilizes a delay-locked loop (DLL) to generate a fixed-phase difference between the input reference clock and its output clock. It is capable of maintaining a stable output frequency even when the input reference frequency varies. When the input reference frequency changes, the DLL automatically adjusts the phase of the output clock to keep it properly aligned with the input clock, enabling the system designed to rely on the clock to remain stable. The device also features a programmable output multiplexer that enables it to divide its output frequency by integers ranging from 1 to 1023.
The ABMJB-902-Q74USY-T3 utilizes an on-chip programmable temperature-compensated voltage-controlled oscillator (TCVCXO). This TCVCXO enables it to accurately determine the output frequency and ensure its stability across a wide range of temperatures. The device also features an on-chip temperature sensor that allows it to continuously monitor and make adjustments to its output frequency as needed in order to maintain accuracy. The device\'s on-chip crystal oscillator provides an optional low-phase-noise and low-jitter source.
Summary
The ABMJB-902-Q74USY-T3 is a Clock Generator, PLL, or Frequency Synthesizer that is used in telecommunication systems, data processing systems, military systems, and entertainment electronics. It utilizes a delay-locked loop and a programmable output multiplexer to generate a wide range of frequencies and voltage levels.
