NB7L32M: ÷·2 Divider with CML Output

  • The NB7L32M is an integrated /2 divider with differential clock inputs and asynchronous reset.

    Differential clock inputs incorporate internal 50 Ω termination resistors and accept LVPECL (Positive ECL), CML, or LVDS. The high frequency reset pin is asserted on the rising edge. Upon power-up, the internal flip-flops will attain a random state; the reset allows for the synchronization of multiple NB7L32M's in a system.

    The differential 16 mA CML output provides matching internal 50 Ω termination which guarantees 400 mV output swing when externally receiver terminated 50 Ω to VCC (See Figure 16).

    The device is housed in a small 3x3 mm 16 pin QFN package.
