Product Overview NB7L32M: ?·2 Divider with CML Output For complete documentation, see the data sheet Product Description 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.
