Features and Applications

The NB4L52 is a differential Data and Clock D flip−flop with a differential asynchronous Reset. The differential inputs incorporate internal 50 Ω 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.

Key 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 Peak−to−Peak, Typical
  • Operating Range: VCC = 2.375 V to 5.5 V with VEE = 0 V
  • Internal Input Termination Resistors, 50 Ω
  • 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 Pb−Free Devices


  • High Performance Logic for ATE and Networking
