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 at 14V for CLK4

Note 3

Output duty cycle is measured at VDD 2 for CLK1 and CLK2 While it is measured at 14V for CLK4

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 702 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

Note 6

Cycle to Cycle Jitter is measured at VCC2

Note 7

Cycle to Cycle Jitter for CLK2 and CLK4 is only for 25 C 5V measured
