Description The NB4L339 is a multi−function Clock generator featuring a 2:1
Clock multiplexer front end and simultaneously outputs a selection of four different divide ratios from its four divider blocks; ÷1/÷2/÷4/÷8.
One divide block has a choice of ÷1 or ÷ 2.
The output of each divider block is fanned−out to two identical differential LVPECL copies of the selected clock.
All outputs provide standard LVPECL voltage levels when externally terminated with a 50−ohm resistor to VCC − 2 V.
The differential Clock inputs incorporate internal ...
