HMC844LC4B v01.0710 HIGH SPEED LOGIC - SMT 7 45 Gbps, XOR / XNOR w/ PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC844LC4B is ideal for: Supports High Data Rates: up to 45 Gbps • RF ATE Applications Differential & Singe-Ended Operation • Broadband Test & Measurement Fast Rise and Fall Times: 11 / 10 ps • Serial Data Transmission up to 45 Gbps Low Power Consumption: 510 mW • Digital Logic Systems up to 25 GHz Programmable Differential Output Voltage Swing: 200 - 850 mVp-p Single Supply: -3.3V 24 Lead 4x4 mm SMT Package: 16 mm2 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. Electrical Specifications, TA = +25°C, Vee = -3.3V Parameter Conditions Min.
