NB4L52
2.5 V/3.3 V/5.0 V Differential
Data/Clock D Flip-Flop
with Reset
MultiLevel Inputs to LVPECL Translator
w/ Internal Termination
The NB4L52 is a differential Data and Clock D flipflop with a
differential asynchronous Reset. The differential inputs incorporate
internal 50 W termination resistors and will accept PECL, LVPECL,
LVCMOS, LVTTL, CML, or LVDS logic levels. When Clock
transitions from Low to High, Data will be transferred to the
differential LVPECL outputs. The differential Clock inputs allow the
NB4L52 to also be used as a negative edge triggered device. The
device is housed in a small 3x3 mm 16 pin QFN package.
Features
Maximum Input Clock Frequency > 4 GHz Typical
330 ps Typical Propagation Delay
145 ps Typical Rise and Fall Times
Differential LVPECL Outputs, 750 mV PeaktoPeak, Typical
Operating Range: VCC = 2.375 V to 5.5 V with VEE = 0 V
Internal Input Termination Resistors, 50 W
Functionally Compatible with Existing 2.5 V/3.3 V/5.0 V LVEL,
LVEP, EP, and SG Devices
40°C to +85°C Ambient Operating Temperature
These are PbFree Devices

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
4. LVPECL outputs loaded with 50 W to VCC – 2.0 V for proper operation.
5. Input and output parameters vary 1:1 with VCC.
6. Vth is applied to the complementary input when operating in singleended mode.
7. VCMRMIN varies 1:1 with VEE, VCMRMAX varies 1:1 with VCC. The VCMR range is referenced to the most positive side of the differential input
signal.
