126572-HMC940LC4B

HMC940LC4B v03.0322 High Speed Digital Logic - SMT 13 Gbps, 1:4 FANOUT BUFFER w/ PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC940LC4B is ideal for: Inputs Terminated Internally in 50 Ohms • RF ATE Applications Differential Inputs are DC Coupled • Broadband Test & Measurement Propagation Delay: 101 ps • Serial Data Transmission up to 13 Gbps Fast Rise and Fall Times: 26 / 25 ps • Clock Buffering up to 13 GHz Programmable Differential Output Voltage Swing: 600 - 1400 mV Power Dissipation: 440 mW 24 Lead Ceramic 4x4 mm SMT Package: 16 mm 2 Functional Diagram General Description The HMC940LC4B is a 1:4 Fanout Buffer designed to support data transmission rates up to 13 Gbps, and clock frequencies as high as 13 GHz. All differential inputs and outputs are DC coupled and terminated on chip with 50 Ohm resistors to ground. The outputs may be used in either single-ended or differential modes, and should be AC or DC coupled into 50 Ohm resistors connected to ground. The HMC940LC4B also features an output level control pin, VR which allows for loss compensation or for signal level optimization. The HMC940LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant 4x4 mm SMT package.
