www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS813001I DUAL VCXO W/3.3V, 2.5V LVPECL FEMTOCLOCK™ PLL FEATURES One 3.3V or 2.5V LVPECL output pair Two selectable crystal oscillator interfaces for the VCXO, one differential clock or one LVCMOS/LVTTL clock inputs CLK1/nCLK1 supports the following input types: LVPECL, LVDS, LVHSTL, SSTL, HCSL Crystal operating frequency range: 14MHz - 24MHz VCO range: 490MHz - 640MHz Output frequency range: 40.83MHz - 640MHz VCXO pull range: ±100ppm (typical) Supports the following applications (among others): SONET, Ethernet, Fibre Channel, HDTV, MPEG RMS phase jitter @ 622.08MHz (12kHz - 20MHz): 0.84 (typical) Supply voltage modes: VCC/VCCO 3.3V/3.3V 3.3V/2.5V 2.5V/2.5V -40°C to 85°C ambient operating temperature Available in both, Standard and RoHS/Lead-Free compliant packages GENERAL DESCRIPTION The ICS813001I is a dual VCXO + FemtoClock™ Multiplier designed for use in Discrete PLL HiPerClockS™ loops. Two selectable external VCXO crystals allow the device to be used in multi-rate applications, where a given line card can be switched, for example, between 1Gb Ethernet (125MHz system reference clock) and 1Gb Fibre Channel (106.25MHz system reference clock) modes. Of course, a multitude of other applications are also possible such as switching between 74.25MHz and 74.175824MHz for HDTV, switching between SONET, FEC and non FEC rates, etc. IC S The ICS813001I is a two stage device – a VCXO followed by a Femto...
