5 / 6 page  CGS700 (Continued) Note 1 trise and tfall parameters are measured at the pin of the device Note 2 Skew is measured at 50% of VCC for CLK1 and CLK2 while it is measured 14V for CLK4 Limits are guaranteed by design Note 3 Output duty cycle is measured at VDD 2 for CLK1 and CLK2 while it is measured 14V for CLK4 Limits are guaranteed by design Note 4 Jitter parameter is characterized and is guaranteed by design only It measures the uncertainty of either the positive or the negative edge over 1000 cycles It is also measured at output levels of VCC 2 Refer to Figure 2 for further explanation Note 5 The GNDA pins of the 700 must be as free of noise as possible for minimum jitter Separate analog ground plane is recommended for the PCB Also the VCCA pin requires extra filtering to further reduce noise Ferrite beads for filtering and bypass capacitors are suggested for VCCA pin TLF11955 – 5 TLF11955 – 6 TLF11955 – 7 FIGURE 1 Waveforms TLF11955 – 8 Jitter e lPeriod(1) b Period(na1)l e 300 ps for either the rising or falling edge where n is 1 to 1000 cycles FIGURE 2 Jitter Application References and Bibliography Information relating to EMI as well as general application issues are in the following application notes AN-988EMI App Note AN-640 AN-991 http www nationalcom 5 |
