ASM3P623S00A/B/C/D/E/F July 2005 rev 1.0 Zero Cycle Slip Peak EMI reduction IC General Features All parts have on-chip PLLs that lock to an input clock on Input frequency range: 20MHz - 50MHz. Zero input - output propagation delay. Low-skew outputs. the CLKIN pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad, internal to the device. Output-output skew less than 250pS. Device-device skew less than 700pS. Multiple ASM3P623S00D/E/F devices can accept the same input clock and distribute it. In this case, the skew between Less than 200pS cycle-to-cycle jitter is compatible with Pentium® based systems. Available in 16pin, 150mil SOIC, 4.4mm TSSOP (ASM3P623S00D/E/F), and in 8pin, 150 mil SOIC, 4.4mm TSSOP Packages (ASM3P623S00A/B/C). 3.3V operation Advanced 0.35µ CMOS technology. The First True Drop-in Solution. the outputs of the two devices is guaranteed to be less than 700pS. All outputs have less than 200pS of cycle-to-cycle jitter. The input and output propagation delay is guaranteed to be less than 250pS, and the output-to-output skew is guaranteed to be less than 250pS. Please refer “Differential Cycle Slips and Spread Spectrum Control Table” for deviations and differential Cycle Slips for ASM3P623S00A/B/C and the ASM3P623S00D/E/F Functional Description devices ASM3P623S00D/E/F is a versatile, 3.3V zero-delay buffer designed to distribute high-speed clocks. It accepts one The ASM3P623S00A/B/C and the ASM3P623S00D/E/F reference input and drives out eight low-skew clocks. It is are available in two different configurations, as shown in available in a 16pin package. The ASM3P623S00A/B/C is the ordering information table. the eight-pin version of the ASM3P623S00. It accepts one reference input and drives out one low-skew clock.

CLKOUT ASM3P623S00A/B/C/D/E/F July 2005 rev 1.0 Spread Spectrum Frequency Generation The clocks in digital systems are typically square waves PCBs etc. These methods are expensive. Spread with a 50% duty cycle and as frequencies increase the spectrum clocking reduces the peak energy by reducing edge rates also get faster. Analysis shows that a square the Q factor of the clock. This is done by slowly wave is composed of fundamental frequency and modulating the clock frequency. The ASM3P623S00X harmonics. The fundamental frequency and harmonics uses the center modulation spread spectrum technique in generate the energy peaks that become the source of which the modulated output frequency varies above and EMI. Regulatory agencies test electronic equipment by below measuring the amount of peak energy radiated from the modulation rate. With center modulation, the average equipment. In fact, the peak level allowed decreases as frequency is the same as the unmodulated frequency and the frequency increases. The standard methods of there is no performance degradation the reference frequency with a specified reducing EMI are to use shielding, filtering, multi-layer Cycle Slip Cycle slip occurs when the output clock edge modulation cycle. Integral cycle slip occurs due to the ‘wanders’ away from the corresponding input clock accumulation of the cycle slip over successive modulation edge. There are two types of cycle slips – a Differential cycles. In ASM3P623S00A/B/C/D/E/F the differential cycle cycle slip and an Integral cycle slip. The differential slip is within the value mentioned in the “Differential Cycle cycle slip is caused due the clock edge variation over Slip and Spread Spectrum Control Table” and the Integral one modulation cycle. It is defined by the maximum Cycle Slip is ‘Zero’. amount of ‘wander’ the clock edge will have within one Pin Configuration 1 CLKIN NC 2 SS% 3 GND 4 ASM3P623S00A/B/C 8 NC 7 VDD 6 CLKOUT 5 SSON CLKIN 1 16 CLKOUT8 CLKOUT1 2 15 CLKOUT7 VDD 3 14 CLKOUT6 SS% 4 GND 5 ASM3P623S00 D/E/F 13 VDD 12 GND CLKOUT2 6 11 CLKOUT5 CLKOUT3 7 10 CLKOUT4 DLY CNTRL 8 9 SSON Zero Cycle Slip Peak EMI Reduction IC Notice: The information in this document is subject to change without notice. 2 of 16 ASM3P623S00A/B/C/D/E/F July 2005 rev 1.0 Pin Description for ASM3P623S00A/B/C Pin # Pin Name 2 1 CLKIN 2 NC Input reference frequency, 5V-tolerant input No Connect 4 3 SS% 4 GND 5 Description Spread Spectrum Selection Ground 4 SSON Spread Spectrum enable and disable option When SSON is HIGH, the spread spectrum is enabled and when LOW, it turns off the spread spectrum. 6 CLKOUT 1,3 Buffered clock output 7 VDD 3.3V supply 8 NC No Connect Pin Description for ASM3P623S00D/E/F Pin # 1 Pin Name 2 CLKIN Input reference frequency, 5V tolerant input 3 2 CLKOUT1 3 VDD SS% 5 GND 6 Spread Spectrum Selection Ground 3 Buffered clock output 3 Buffered clock output CLKOUT2 7 CLKOUT3 8 DLY CNTRL 9 SSON4 10 spectrum is enabled and when LOW, it turns off the spread spectrum.
