ICS84025 CRYSTAL-TO-LVCMOS / LVTTL FREQUENCY SYNTHESIZER WITH FANOUT BUFFER PRELIMINARY GENERAL DESCRIPTION The ICS84025 is a Crystal-to-LVCMOS/LVTTL Frequency Synthesizer with Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The VCO frequency is programmed in steps equal to the value of the crystal frequency. The VCO and output frequency can be programmed using the feedback and output frequency select pins. The low phase noise character- istics of the ICS84025 make it an ideal clock source for Fibre Channel 1 and Gigabit Ethernet applications. BLOCK DIAGRAM PIN ASSIGNMENT FEATURES • 6 LVCMOS/LVTTL outputs • Crystal oscillator interface • Output frequency range: 53.125MHz to 125MHz • Crystal input frequency: 25MHz and 25.5MHz • RMS phase jitter at 106.25, using a 25.5MHz crystal (637KHz to 10MHz): 3.25ps • Phase noise: Offset Noise Power 100Hz ................. -100 dBc/Hz 1KHz ................. -115 dBc/Hz 10KHz ................. -125 dBc/Hz 100KHz ................. -127 dBc/Hz • 3.3V core, outputs may either be 3.3V, 2.5V or 1.8V • 0°C to 70°C ambient operating temperature • Industrial temperature information available upon request HiPerClockS™ ,&6 Q0:Q5 PLL 6/ Feedback Divider OSC Output Divider 0 1 XTAL1 XTAL2 F_SEL1 PLL_SEL MR F_SEL0 ICS84025 24-Lead, 300-MIL SOIC 7.5mm x 15.33mm x 2.3mm body package M Package Top View VDDO Q0 GND Q1 VDDO Q2 GND Q3 VDDO Q4 GND Q5 1 2 3 4 5 6 7 8 9 10 11 12 F_SEL0 F_SEL1 MR XTAL1 XTAL2 GND VDDA VDD PLL_SEL GND nc VDDO 24 23 22 21 20 19 18 17 16 15 14 13 FUNCTION TABLE s t u p n IL A T Xy c n e u q e r F t u p t u O R M1 L E S _ F0 L E S _ FT U O _ F 1X X W O L 00 0 z H M 5 . 5 2z H M 5 2 1 . 3 5 00 1 z H M 5 . 5 2z H M 5 2 . 6 0 1 01 0 z H M 5 2z H M 5 . 2 6 01 1 z H M 5 2z H M 5 2 1 The Preliminary Information presented herein represents a product in prototyping or pre-production.
