The supply voltage accepts 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without an extra regulator.
Active current is 50 mA typical at full swing.
Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Surface-mount reflow profile follows standard lead-free solder.
LVPECL (Low-Voltage Positive Emitter-Coupled Logic). The output swing is differential and requires a 50-ohm termination to Vcc - 2V. Do not leave the complementary output floating — terminate both pins symmetrically.
±50 ppm over the full -20°C to 70°C operating range. This includes initial tolerance, temperature drift, and aging over 10 years. For a 46.875 MHz clock, that is a worst-case drift of ±2.34 kHz.
