HMC910LC4B v02.0910 BROADBAND ANALOG TIME DELAY, DC - 24 GHz Typical Applications Features The HMC910LC4B is ideal for: Very Wide Bandwidth: DC - 24 GHz • Synchronization of clock and data Continuous Adjustable Delay Range: 70 ps • Transponder design Single-Ended or Differential Operation • Serial Data Transmission up to 32 Gbps Adjustable Differential Output Voltage Swing: 170 - 760 mVp-p @ 24 GHz • Broadband Test & Measurement Delay Control Modulation Bandwidth: 10 MHz • RF ATE Applications Single Supply: +3.3V 24 Lead Ceramic 4x4mm SMT Package: 16mm² Broadband time delay - analog - SMT 13 13 - 1 Functional Diagram General Description The HMC910LC4B is a broadband time delay with 0 to 70 ps continuously adjustable delay range. The delay control is linearly monotonic with respect to the control voltage, VDC and the control input has a modulation bandwidth of 10 MHz. The device provides a differential output voltage with constant amplitude for single-ended or differential input voltages above the input sensitivity level, while the output voltage swing may be adjusted using the VAC control pin. The HMC910LC4B features internal temperature compensation and bias circuitry to minimize delay variations with temperature. The device also features an enable pin, ENB. All RF input and outputs of the HMC910LC4B are internally terminated with 50 Ohms to Vcc, and may either be AC or DC coupled. Output pins can be connected directly to a 50 Ohm to Vcc terminated system, while DC blocking capacitors must be used if the terminated system input is 50 Ohms to a DC voltage other than Vcc.
