All clock outputs meet Intel’s drive strength, rise/fall times, jitter, accuracy, and skew requirements. HCLK3 16 HCLKB3 17 VDD 18 The part possesses a dedicated power-down input pin for power management control. This input is synchronized on chip, and ensures glitch-free output transitions. In addition, the part can be configured to disable the 48 MHz outputs for lower power operation and an increase in the performance of the functioning outputs. The IOCLK and REFCLK can also be disabled for the highest performance of the Host outputs. 39 HCLK5 38 HCLKB5 37 VDD 36 HCLK6 35 HCLKB6 34 VSS 33 HCLK7 32 HCLKB7 31 VDD REFCLK/SELC 19 30 MULTSEL0 SPREAD 20 29 MULTSEL1 VSS 21 28 VSS XIN 22 27 VSSA XOUT 23 VDD 24 26 IREF 25 VDDA SW00665 ORDERING INFORMATION PACKAGES TEMPERATURE RANGE ORDER CODE DRAWING NUMBER 48-Pin Plastic TSSOP 0°C to +70°C PCK2022R DGG SOT362-1 Intel and Pentium III are trademarks of Intel Corporation. 2000 Nov 13 2 853–2225 25005 Philips Semiconductors Product specification CK00 (100/133 MHz) spread spectrum differential system clock generator PCK2022R PIN DESCRIPTION PIN(S) SYMBOL FUNCTION 1 IOCLK Dual frequency pin which can operate at either 33 MHz or 66 MHz per the selection table. 3, 4 48M_0/SELA 48M_1/SELB 3.3 V fixed 48 MHz clock outputs.

Output drivers must have monotonic rise/fall times through the specified VOL/VOH levels. 2. Period, jitter, offset, and skew measured on rising edge at 1.5 V for 3.3 V clocks. 3. The IOCLK clock is the Host clock divided by 4 in 33 MHz mode and divided by 2 in 66 MHz mode at Host = 133 MHz. IOCLK clock is the Host clock divided by 3 in 33 MHz and divided by 2/3 in 66 MHz mode at Host = 100 MHz. 4. Frequency accuracy of 48 MHz must be +167 ppm to match USB default. 5. tHKH is measured at 2.4 V for 3.3 V outputs, as shown in Figure 7. 6. tHKL is measured at 0.4 V for all outputs as shown in Figure 7. 7. the time is specified from when VDDQ achieves its normal operating level (typical condition VDDQ = 3.3 V) until the frequency output is stable and operating within specification. 8. tRISE and tFALL are measured as a transition through the threshold region VOL = 0.4 V and VOH = 2.4 V (1 mA) JEDEC specification. 9. The average period over any 1 µs period of time must be greater than the minimum specified period. 10. Calculated at minimum edge rate (1 V/ns) to guarantee 45–55% duty cycle. Pulse width is required to be wider at faster edge rate to ensure duty specification is met. 11. Test load is RS = 33.2 Ω, RP = 49.9 Ω. 12. Must be guaranteed in a realistic system environment. 13. Configured for VOH = 0.71 V in a 50 Ω environment. 14. Measured at crossing points. 15. Measured at 20% to 80%. 16. Determined as a fraction of 2*(tRP – tRN) / (tRP + tRN), where tRP is a rising edge, and tRN is an intersecting falling edge. 17. Frequency generated by crystal oscillator 18. Voltage measure point (VM = 1.5 V). VDD = 3.3 V. 19. All offsets are to be measured at rising edges. 20.
