Preliminary PLL502-67 4 Outputs 12.5MHz - 200MHz Low Phase Noise Multiplier VCXO FEATURES * * * * * * * * * Selectable 12.5MHz to 200MHz range. Low phase noise output (@ 10kHz frequency offset, -140dBc/Hz for 17.664MHz, -132dBc/Hz for 35.328MHz, -125dBc/Hz for 155.52MHz). 4 CMOS outputs (in phase). 12 to 25MHz crystal input. No external load capacitor or varicap required. Wide pull range (+/-190 ppm) Selectable 1/2 to 8x frequency multiplier. 3.3V operation. Available in 14-SOP.

It provides phase noise performance as low as -140dBc at 1kHz offset (at 17.664MHz) and -125dBc at 1kHz offset at 155.52MHz by multiplying the input crystal frequency up to 8x. The wide pull range (+/- 190 ppm) and very low jitter makes this chip ideal for a wide range of applications, from xDSL to SONET/SDH and FEC. The chip accepts a low cost fundamental parallel resonant mode crystal from 12 to 25MHz. ^: Internal pull-up BLOCK DIAGRAM SEL CLK4 VCON XIN XOUT Oscillator Amplifier w/ integrated varicaps PLL (Phase Locked Loop) CLK3 CLK2 CLK1 PLL by-pass PLL502-67 47745 Fremont Blvd., Fremont, California 94538 TEL (510) 492-0990 FAX (510) 492-0991 Rev 02/20/03 Page 1 Preliminary PLL502-67 4 Outputs 12.5MHz - 200MHz Low Phase Noise Multiplier VCXO FREQUENCY SELECTION TABLE SEL2 0 0 0 0 1 1 1 1 SEL1 0 0 1 1 0 0 1 1 SEL0 0 1 0 1 0 1 0 1 Reserved Reserved Reserved Fin x 2 Fin / 2 Fin x 4 Fin x 8 No multiplication Selected Multiplier Note: Internal pull-ups default SEL2, SEL1 and SEL0 to `1' if not connected PIN DESCRIPTIONS Name XIN XOUT VCON GND CLK1, CLK2 CLK3, CLK4 SEL2 SEL1 SEL0 VDD Pin number 2 3 6 7,8 9,10 12,13 4 5 14 1, 11 Type I I I P O O I I I P Crystal in connector.

It is assumed that the crystal will be at nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This however may reduce the pull range. 47745 Fremont Blvd., Fremont, California 94538 TEL (510) 492-0990 FAX (510) 492-0991 Rev 02/20/03 Page 3 Preliminary PLL502-67 4 Outputs 12.5MHz - 200MHz Low Phase Noise Multiplier VCXO 3.
