841N4830 - NG Crystal-to-HCSL Frequency Synthesizer

Datasheet Summary

Description

The 841N4830 is a 3 HCSL, 1 LVPECL and 2 LVCMOS output Synthesizer optimized to generate PCI Express reference clock frequencies.

The device uses IDT’s fourth generation FemtoClock® NG technology for synthesis of high clock frequency at very low phase noise.

Features

Fourth generation FemtoClock® Next Generation (NG) technology.
Three differential HCSL outputs, one differential LVPECL and two single-ended LVCMOS/LVTTL outputs.
Crystal oscillator interface designed for a 25MHz, 12pF parallel resonant crystal.
CLK/nCLK input pair can accept the following differential input levels: LVPECL, LVDS, HCSL.
A 25MHz crystal generates output frequencies of: 100MHz, 50MHz and 25MHz.
VCO frequency: 2GHz.

FemtoClock® NG Crystal-to-HCSL Frequency Synthesizer 841N4830 Datasheet General Description The 841N4830 is a 3 HCSL, 1 LVPECL and 2 LVCMOS output Synthesizer optimized to generate PCI Express reference clock frequencies. The device uses IDT’s fourth generation FemtoClock® NG technology for synthesis of high clock frequency at very low phase noise. It provides low power consumption with good power supply noise rejection. Using a 25MHz, 12pF parallel resonant crystal, the following frequencies can be generated: 100MHz, 50MHz and 25MHz. Maximum rms phase jitter of 0.36ps, easily meets PCI Express jitter requirements. The 841N4830 is packaged in a small 32-pin VFQFN package.
