NB4N527S
3.3V, 2.5Gb/s Dual
AnyLevel™ to LVDS
Receiver/Driver/Buffer/
Translator with Internal
Input Termination
http://onsemi.com
NB4N527S is a clock or data Receiver/Driver/Buffer/Translator
capable of translating AnyLevelTM input signal (LVPECL, CML,
HSTL, LVDS, or LVTTL/LVCMOS) to LVDS. Depending on the
distance, noise immunity of the system design, and transmission line
media, this device will receive, drive or translate data or clock signals
up to 2.5 Gb/s or 1.5 GHz, respectively.
The NB4N527S has a wide input common mode range of
GND + 50 mV to VCC − 50 mV combined with two 50 W internal
termination resistors is ideal for translating differential or
single−ended data or clock signals to 350 mV typical LVDS output
levels without use of any additional external components (Figure 6).
The device is offered in a small 3 mm x 3 mm QFN−16 package.
NB4N527S is targeted for data, wireless and telecom applications as
well as high speed logic interface where jitter and package size are
main requirements. Application notes, models, and support
documentation are available on www.onsemi.com.

Exposed pad. EP on the package bottom is thermally connected to the die
improved heat transfer out of package. The pad is not electrically connected
to the die, but is recommended to be soldered to GND on the PCB.
1. In the differential configuration when the input termination pins(VTD0/VTD0, VTD1/ VTD1) are connected to a common termination voltage
or left open, and if no signal is applied on D0/D0, D1/D1 input, then the device will be susceptible to self−oscillation.
