ICS9169-01 Frequency Generator and Integrated Buffers for Intel Pentium µµ and Pentium ProTM µP's General Description Features The ICS9169-01 generates all clocks required for high speed RISC or CISC microprocessor systems such as 486, Pentium/ Pentium Pro™, PowerPC™, etc. Four different reference frequency multiplying factors are externally selectable with smooth frequency transitions. These multiplying factors can be customized for specific applications. A test mode is provided to drive all clocks directly. • High drive BCLK outputs typically provide greater than 1V/ ns slew rate into 30pF loads. PCLK outputs typically provide better than 1V/ns slew rate into 20pF loads while maintaining 50±5% duty cycle. The REF clock outputs typically provide better than 0.5V/ns slew rates. • • • • • • • • Generates four processor, six bus, three 14.318 MHz and one 48 MHz clock for ISA bus, audio, super I/O and bus bridge devices Supports the Intel MARS chip set Synchronous clocks skew matched to 250ps window on PCLKs and 500ps window on BCLKs Test clock mode eases system design Selectable multiplying ratios Custom configurations available Output frequency ranges to 100 MHz (depending on option) 3.0V - 5.5 V supply range 28-pin SOIC and 28-pin SSOP (209-mil) packages Applications • Ideal for high-speed RISC or CISC systems such as 486, Pentium, Pentium Pro, PowerPC, etc. Block Diagram PLL CLOCK GEN X2 X1 48 MHz XTAL OSC REF(0:2) OEN FS0 FS1 PLL CLOCK GEN SYNC PCLK(0:3) REG BCLK(0:5) Pentium is a trademark of Intel Corporation PowerPC is a trademark of Motorola Corporation ICS9169-01 Pin Configuration Functionality FS1 FS0 *VCO 0 0 1 1 0 1 0 1 230/33x X1 212/23x X1 176/21x X1 Test mode X1, REF (MHz) 14.31818 14.31818 14.31818 TCLK PCLK(0:3) (MHz) 50 (49.7) 66 (66.5) 60 (59.9) TCLK/2 *VCO range is limited from 60 - 200 MHz PCLK(0:3) VCO/2 TCLK/2 BCLK(0:5) PCLK/2 TCLK/4 48 MHz 48 MHz TCLK/2 28 Pin SOIC 28 Pin SSOP Pin Descriptions PIN NUMBER PIN NAME TYPE 2 X1 IN 3 4, 11, 23 X2 GND OUT PWR DESCRIPTION XTAL or external reference frequency input.

Notes: 1) All clock outputs should have series terminating resistor. Not shown in all places to improve readibility of diagram. 2) 47 ohm / 56pf RC termination should be used at 50MHz and higher clock loads. 3) Optional crystal load capacitors are recommended.
