ICS843021I-01 Datasheet | Integrated Device Technology

Features - - - - - - - - One differential 3.3V or 2.5V LVPECL output Crystal oscillator interface designed for 25MHz, 18p F parallel resonant crystal Output frequency range: 125MHz, using a 25MHz crystal VCO range: 490MHz - 640MHz RMS phase jitter @ 125MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.41ps (typical) Full 3.3V or 2.5V operating supply -40°C to 85°C ambient operating temperature Available in both standard (Ro HS 5) and lead-free (Ro HS 6) packages General Description The ICS843021I-01 is a Gigabit Ethernet Clock Generator and a member of the Hi Per Clocks TM Hi Per Clock S™ family of high performance devices from IDT. The ICS843021I-01 uses a 25MHz crystal to synthesize 125MHz. The ICS843021I-01 has excellent phase jitter performance, over the 1.875MHz - 20MHz integration range. The ICS843021I-01 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space. Block Diagram OE Pullup 25MHz Pin Assignment VCC XTAL_OUT XTAL_IN VEE 1 2 3 4 8 7...
