ICS843004-01 FEMTOCLOCKS™CRYSTAL-TO- 3.3V LVPECL FREQUENCY SYNTHESIZER GENERAL DESCRIPTION The ICS843004-01 is a 4 output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, 62.5MHz. The ICS843004-01 uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The ICS843004-01 is packaged in a small 24-pin TSSOP package. FEATURES • Four 3.3V LVPECL outputs • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input • Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz • VCO range: 560MHz - 680MHz • RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.57ps (typical) • RMS phase noise at 156.25MHz (typical) Phase noise: Offset Noise Power 100Hz ............... -95.5 dBc/Hz 1KHz ................ -118 dBc/Hz 10KHz ................ -126 dBc/Hz 100KHz .............. -126.6 dBc/Hz • Full 3.3V supply mode • -30°C to 85°C ambient operating temperature HiPerClockS™ ICS PIN ASSIGNMENT 1 1 0 1 0 Phase Detector VCO 625MHz (w/25MHz Reference) OSC M = 25 (fixed) F_SEL[1:0] 0 0 ÷4 0 1 ÷5 1 0 ÷10 1 1 not used 2 ICS843004-01 24-Lead TSSOP 4.40mm x 7.8mm x 0.92mm package body G Package Top View nQ1 Q1 VCCo Q0 nQ0 MR nPLL_SEL nc VCCA F_SEL0 VCC F_SEL1 1 2 3 4 5 6 7 8 9 10 11 12 nQ2 Q2 VCCO Q3 nQ3 VEE VCC nXTAL_SEL TEST_CLK VEE XTAL_IN XTAL_OUT 24 23 22 21 20 19 18 17 16 15 14 13 BLOCK DIAGRAM s t u p n I y c n e u q e r F t u p t u O ) . f e R z H M 5 2 ( 1 L E S _ F0 L E S _ F r e d i v i D M e u l a V r e d i v i D N e u l a V N / M e u l a V r e d i v i D 00 5 24 5 2 . 65 2 . 6 5 1 01 5 25 5 5 2 1 10 5 20 15 . 25 . 2 6 11 5 2d e s u t o nd e s u t o n FREQUENCY SELECT FUNCTION TABLE F_SEL[1:0] nPLL_SEL TEST_CLK XTAL_IN XTAL_OUT nXTAL_SEL MR Q0 nQO Q1 nQ1 Q2 nQ2 Q3 nQ3 Pulldown Pulldown 25MHz Pulldown Pulldown Pulldown |
