Femtoclock™ Crystal-to-HSTL Clock
Generator
842023
DATA SHEET
General Description
The 842023 is an Ethernet Clock Generator. For Ethernet
applications, a 25MHz crystal is used to generate 250MHz. The
842023 uses IDT 3
rd
generation low phase noise VCO technology
and can achieve <1ps rms phase jitter, easily meeting Ethernet jitter
requirements. The 842023 is packaged in a small 8-pin TSSOP,
making it ideal for use in systems with limited board space.
Features
One differential HSTL output pair
Crystal oscillator interface, 18pF parallel resonant crystal
(24.5MHz – 34MHz)
Output frequency range: 245MHz – 340MHz
VCO range: 490MHz – 680MHz
RMS phase jitter at: 250MHz, using a 25MHz crystal (1.875MHz –
20MHz): 0.36ps (typical)
Full 3.3V or 2.5V output supply modes
0°C to 70°C ambient operating temperature
Available in lead-free (RoHS 6) packaging
