NB6N239S
3.3 V, 3.0 GHz Any
Differential Clock IN to
LVDS OUT ÷1/2/4/8, ÷2/4/8/16
Clock Divider
Description
The NB6N239S is a high−speed, low skew clock divider with two
divider circuits, each having selectable clock divide ratios; B1/2/4/8
and B2/4/8/16. Both divider circuits drive LVDS compatible outputs.
(More device information on page 7). The NB6N239S is a member
of the ECLinPS MAX™ family of high performance clock products.
Features
• Maximum Clock Input Frequency, 3.0 GHz (1.5 GHz with B1)
• Input Compatibility with LVDS/LVPECL/CML/HSTL/HCSL
• Rise/Fall Time 120 ps Typical
• < 5 ps Typical Within Device Output Skew
• Example; 622.08 MHz Input Generates 38.88 MHz to 622.08 MHz
Outputs
• Internal 50 W Termination Provided
• Random Clock Jitter < 2 ps RMS
• QA B1 Edge Aligned to QB Bn Edge
• Operating Range: VCC = 3.0 V to 3.465 V with GND = 0 V
• Master Reset for Synchronization of Multiple Chips
• VBBAC Reference Output
• Synchronous Output Enable/Disable
• TIA/EIA − 644 Compliant
• These Devices are Pb−Free and are RoHS Compliant
