NB3L8504S
2.5 V / 3.3 V 1:4 Differential
Input to LVDS Fanout Buffer
/ Translator
Description
The NB3L8504S is a differential 1:4 LVDS fanout buffer/translator
with OE control for each differential output. The differential inputs
which can be driven by either a differential or single−ended input, can
accept various logic level standards such as LVPECL, LVDS, HSTL,
HCSL and SSTL. These signals are then translated to four identical
LVDS copies of the input up to 700 MHz. As such, the NB3L8504S is
ideal for Clock distribution applications that require low skew.
The NB3L8504S is offered in the TSSOP−16 package.
Features
• Four Differential LVDS Outputs
• Each Differential Output has OE Control
• 700 MHz Maximum Output Frequency
• 660 ps Max Output Rise and Fall Times, LVCMOS
• Translates Differential Input to LVDS Levels
• Additive Phase Jitter RMS: < 100 fs Typical
• 50 ps Maximum Output Skew
• 350 ps Maximum Part−to−part Skew
• 1.3 ns Maximum Propagation Delay
• Operating Range: VCC = 2.5 V ± 5% or 3.3 V ± 10%
• −40°C to +85°C Ambient Operating Temperature
• 16−Pin TSSOP, 4.4 mm x 5.0 mm x 0.925 mm
• These are Pb−Free Devices
Applications
• Telecom
• Ethernet
• Networking
• SONET

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
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.
12. Measured by forcing a 50% duty cycle clock source. All LVDS output loading with an external RL = 100 W across Q & Q.
13. VINPP(max) cannot exceed VDD. Input voltage swing is a single−ended measurement operating in differential mode.
14. Skew is measured between outputs under identical transition at 50 MHz.
