NB4L7210
2.5V/3.3V Differential 2x10
Crosspoint Clock Driver
with SDI Programmable
Output Selects
The NB4L7210 is a Clock input crosspoint fanout distribution
device selecting between one of two input clocks on each of the 10
differential output pairs. A 10 Bit Serial Data Interface programs each
output MUX to asynchronously select either Input clock.
CLOCK inputs can accept LVCMOS, LVTTL, LVPECL, CML, or
LVDS signal levels and incorporate an internal 50 ohms on die
termination resistors. SCLK, SDATA, and SLOAD input can accept
single ended LVPECL, CML, LVCMOS, LVTTL signals levels.
SCLK and SDATA inputs operate up to 20 MHz. SLOAD input
loads and latches the output select data. The SDATAOUT pin permits
cascading multiple devices. Outputs are optimized for minimal
output−to−output skew and low jitter.
Features
• Typical Input Clock Frequency > 2 GHz
• 200 ps Typical Rise and Fall Times
• 800 ps Typical Propagation Delay
• Output to Output Skew 150 ps
• Additive RMS Phase Jitter of 0.2 ps
• Operating Range: VCC = 2.375 V to 3.6 V with VEE = 0 V
• Differential LVPECL Output Level (Typ 700 mV Peak−to−Peak)
• Low Profile 8x8 mm, 52 QFN Package
• 10GE WAN: 155.52 MHz / 622.08 MHz
• 10GE LAN: 161.1328 MHz
• These are Pb−Free Devices*
