HMC844LC4B

HMC844LC4B v01.0710 45 Gbps, XOR / XNOR w/ PROGRAMMABLE OUTPUT VOLTAGE Features Supports High Data Rates: up to 45 Gbps Differential & Singe-Ended Operation Fast Rise and Fall Times: 11 / 10 ps Low Power Consumption: 510 mW Programmable Differential Output Voltage Swing: 200 - 850 mVp-p Single Supply: -3.3V 24 Lead 4x4 mm SMT Package: 16 mm2 Typical Applications The HMC844LC4B is ideal for: • RF ATE Applications 7 HIGH SPEED LOGIC - SMT • Broadband Test & Measurement • Serial Data Transmission up to 45 Gbps • Digital Logic Systems up to 25 GHz Functional Diagram General Description The HMC844LC4B is an XOR/XNOR function designed to support data transmission rates of up to 45 Gbps, and clock frequencies as high as 25 GHz. The HMC844LC4B may be easily configured to provide either XOR or XNOR logic functions. The HMC844LC4B also features an output level control pin, VAC, which allows for loss compensation or for signal level optimization. All input signals to the HMC844LC4B are terminated with 50 Ohms-to-ground on-chip, and may be either AC or DC coupled. The differential outputs of the HMC844LC4B may be either AC or DC coupled. Outputs can be connected directly to a 50 Ohms-toground terminated system, while DC blocking capacitors should be used if the terminating system is 50 Ohms to a non-ground DC voltage. The HMC844LC4B operates from a single -3.3V DC supply, and is available in a ceramic RoHS compliant 4x4 mm SMT package.
