The 874003I-03 is a high performance Differential-to-LVDS Frequency Translator/ Jitter Attenuator designed for use in communication systems. In these systems, a jitter attenuator may be required to attenuate high frequency random and deterministic jitter components from the PLL synthesizer and from the system board. The 874003I-03 has a bandwidth that can easily track triangular spread profiles, while providing good jitter attenuation. The 874003I-03 uses IDT's 3RD Generation FemtoClockTM PLL technology to achieve the lowest possible phase noise. The device is packaged in a 20 Lead TSSOP package, making it ideal for use in space constrained applications.
