LOW PHASE NOISE CLOCK MULTIPLIER DATASHEET ICS601-21 The ICS601-21 is a low-cost, low phase noise, high performance clock synthesizer for applications which require low phase noise and low jitter. It is ICS’ lowest phase noise multiplier. Using ICS’ patented analog and digital Phase Locked Loop PLL techniques, the chip accepts a 10 - 27 MHz crystal or clock input, and produces output clocks up to 220 MHz at V. This product is intended for clock generation. It has low output jitter variation in the output period , but input to output skew and jitter are not defined nor guaranteed. • Fully integrated PLL, no external loop filter required • Differential V LVPECL outputs • Uses fundamental 10 - 27 MHz crystal or clock • Output clocks up to 220 MHz at V • Low phase noise -122 dBc/Hz at 10 kHz • Low jitter - 15 ps one sigma typ. • Powerdown mode lowers power consumption • Packaged in 16-pin TSSOP • Advanced, low power, sub-micron CMOS process • Operating voltage of V • Commercial temperature range available • Available in Pb lead free package Block Diagram X1/ICLK Crystal or clock input Reference Divider Crystal Oscillator Phase Comparator Charge Pump Loop Filter ROM Based Multipliers VCO Divide 4 S2:0 CLK nCLK IDT / ICS LOW PHASE NOISE CLOCK MULTIPLIER ICS601-21 ICS601-21 LOW PHASE NOISE CLOCK MULTIPLIER CLOCK MULTIPLIER Pin Assignment Multiplier Select Table GND 8 16 X2 15 GND 14 CLK 13 nCLK 12 VDD 11 S0 10 S1 16 Pin 173 m il TSSOP Pin Descriptions Multiplier x1 x2 x3 x4 x5 x6 x8 x16 0 = connect directly to ground 1 = connect directly to VDD Pin Number 2-4 5 6 7-8 9 10 11 12 13 14 15 16 Pin Name VDD GND VDD GND S2 S1 S0 VDD nCLK CLK GND X2 Pin Type Power Input Power Output Power Pin Description Crystal or clock input.
