SYSTEM PERIPHERAL CLOCK SOURCE DATASHEET ICS650-01 The ICS650-01 is a low-cost, low-jitter, high-performance clock synthesizer for system peripheral applications. Using analog/digital Phase-Locked Loop PLL techniques, the device accepts a parallel resonant MHz crystal input to produce up to eight output clocks. The device provides clocks for PCI, SCSI, Fast Ethernet, Ethernet, USB, and AC97. The user can select one of three USB frequencies and also one of two AC97 audio frequencies. The OE pin puts all outputs into a high impedance state for board level testing. All frequencies are generated with less than one ppm error, meeting the demands of SCSI and Ethernet clocking. • Packaged in 20-pin SSOP QSOP • Available in Pb lead free package • Operating voltage of V or 5 V • Less than one ppm synthesis error in all clocks • Inexpensive MHz crystal or clock input • Provides Ethernet and Fast Ethernet clocks • Provides SCSI clocks • Provides PCI clocks • Selectable AC97 audio clock • Selectable USB clock • OE pin tri-states the outputs for testing • Selectable frequencies on three clocks • Duty cycle of 40/60 • Advanced, low-power CMOS process • Industrial temperature range available NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram VDD 3 2 PSEL1:0 ASEL USEL MHz Crystal or Clock X1/ICLK Crystal Oscillator Clock Synthesis Circuitry 4 Processor Clocks Audio Clock USB Clock 20 MHz 2 GND OE all outputs IDT / ICS SYSTEM PERIPHERAL CLOCK SOURCE ICS650-01 SYSTEM PERIPHERAL CLOCK SOURCE CLOCK SYNTHESIZER Pin Assignment Processor Clock MHz USEL X1/ICLK UCLK ACLK PCLK4 PSEL1 PSEL0 PCLK2 PCLK3 ASEL 14.318M PCLK1 20 pin 150 mil SSOP USB Clock MHz USEL 0 M 1 UCLK 12 24 48 Pin Descriptions PSEL1 0 M 1 PSEL0 0 M 1 0 M 1 0 M 1 Ordering Information E1 E A Symbol A A1 A2 b c D E E1 e L α 1 -C- SEATING PLANE Basic Basic Part / Order Number 650R-01* 650R-01T* 650R-01LF 650R-01LFT 650R-01I* 650R-01IT* 650R-01ILF 650R-01ILFT Marking see page 6 Shipping Packaging Tubes Tape and Reel Tubes Tape and Reel Tubes Tape and Reel Tubes Tape and Reel Package 20-pin SSOP 20-pin SSOP 20-pin SSOP 20-pin SSOP 20-pin SSOP 20-pin SSOP 20-pin SSOP 20-pin SSOP Temperature 0 to +70° C 0 to +70° C 0 to +70° C 0 to +70° C -40 to 85° C -40 to 85° C -40 to 85° C -40 to 85° C *NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 While the information presented herein has been checked for both accuracy and reliability, Integrated Device Technology IDT assumes no responsibility for either its use or for the infringement of any patents or other rights of third parties, which would result from its use.
