Product Overview
NB4L7210: Clock Driver, 2.5 V / 3.3 V Differential 2x10 Crosspoint, with SDI
Programmable Output Selects
For complete documentation, see the data sheet
Product Description
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
