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.
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
RMS Phase Jitter @ 100MHz, (12kHz – 20MHz) using a 25MHz
crystal: 0.36ps (maximum)
Power supply noise rejection PSNR: -45dB (typical)
PCI Express Gen 2 (5 Gb/s) jitter compliant
Full 3.3V supply mode
-40°C to 85°C ambient operating temperature
Available in lead-free (RoHS 6) package
