The NB7V586M is a differential 1-to-6 CML Clock/Data Distribution chip featuring a 2:1 Clock/Data input multiplexer with an input select pin. The INx/INx inputs incorporate internal 50 W termination resistors and will accept differential LVPECL, CML, or LVDS logic levels (see Figure 12). The INx/INx inputs and core logic are powered with a 1.8 V supply. The NB7V586M produces six identical differential CML output copies of Clock or Data. The outputs are configured as three banks of two differential pair. Each bank (or all three banks) have the flexibility of being powered by any combination of either a 1.8 V or 1.2 V supply. The 16 mA differential CML output structure provides matching internal 50 W source terminations and 400 mV output swings when externally terminated with a 50 W resistor to VCCOx (see Figure 11). The 1:6 fanout design was optimized for low output skew and minimal jitter and is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications operating up to 6 GHz or 10 Gb/s typical. The VREFAC reference outputs can be used to rebias capacitor-coupled differential or single-ended input signals.
