NB7V32M
1.8V / 2.5V, 10GHz ÷2 Clock
Divider with CML Outputs
MultiâLevel Inputs w/ Internal
Termination
Description
The NB7V32M is a differential B2 Clock divider with
asynchronous reset. The differential Clock inputs incorporate internal
50 W termination resistors and will accept LVPECL, CML and LVDS
logic levels.
The NB7V32M produces a B2 output copy of an input Clock
operating up to 10 GHz with minimal jitter.
The RESET Pin is asserted on the rising edge. Upon powerâup, the
internal flipâflops will attain a random state; the Reset allows for the
synchronization of multiple NB7V32Mâs in a system.
The 16 mA differential CML output provides matching internal
50 W termination which guarantees 400 mV output swing when
externally receiver terminated with 50 W to VCC .
The NB7V32M is the 1.8 V/2.5 V version of the NB7L32M
(2.5 V/3.3 V) and is offered in a low profile 3 mm x 3 mm 16âpin
QFN package. The NB7V32M is a member of the GigaCommâ¢
family of high performance clock products. Application notes,
models, and support documentation are available at
www.onsemi.com.
