LVPECL CLOCK OSCILLATOR

APPLICATION INFORMATION

TERMINATION FOR 3.3V LVPECL OUTPUT

TERMINATION FOR 2.5V LVPECL OUTPUT

Figure 2A and Figure 2B show examples of termination for 2.ꢀV

LVPECL driver.These terminations are equivalent to terminating ꢀ0Ω

to V_CC- 2V. For V_CC= 2.ꢀV, the V_CC- 2V is very close to ground level.

The R3 in Figure 2B can be eliminated and the termination is shown

in Figure 2C.

The clock layout topology shown below is a typical termination

for LVPECL outputs. The two different layouts mentioned are

recommended only as guidelines.

FOUT and nFOUT are low impedance following outputs that gen-

erate ECL/LVPECL compatible outputs.Therefore, terminating re-

sistors (DC current path to ground) or current sources must be

used for functionality. These outputs are designed to drive ꢀ0Ω

transmission lines. Matched impedance techniques should be

used to maximize operating frequency and minimize signal dis-

tortion. Figures 1A and 1B show two different layouts which are

recommended only as guidelines. Other suitable clock layouts

may exist and it would be recommended that the board designers

simulate to guarantee compatibility across all printed circuit and

clock component process variations.
