HMC749LC3C

The HMC749LC3C is a T Flip-Flop w/Reset designed to support clock frequencies as high as 26 GHz. During normal operation, with the reset pin not asserted, the output toggles from its prior state on the positive edge of the clock. This results in a divide-bytwo function of the clock input. Asserting the reset pin forces the Q output low regardless of the clock edge state (asynchronous reset assertion).

The features of HMC749LC3C are as follows: (1)Supports Clock Frequencies up to 26 GHz; (2)Differential & Singe-Ended Operation; (3)Fast Rise and Fall Times: 18 / 17 ps; (4)Low Power Consumption: 270 mW typ.; (5)Programmable Differential Output Voltage Swing: 600 - 1100 mV; (6)Propagation Delay: 95 ps; (7)Single Supply: +3.3V; (8)16 Lead Ceramic 3x3mm SMT Package: 9mm2.

The electrical characteristics of the HMC749LC3C are: (1)Power Supply Voltage: 3.0 to 3.6 V; (2)Power Supply Current: 82 mA; (3)Maximum clock Rate: 26 GHz; (4)Maximum Clock Rate: 13 GHz; (5)Input High Voltage: 2.8 to 3.8 V; (6)Input Low Voltage: 2.8 to 3.8 V; (7)Input Return Loss Frequency <13 GHz: 10 dB; (8)Output Amplitude: 550 mVpp at Single-Ended, peak-to-peak, 1100 mVpp at Differential, peak-to-peak; (9)Output High Voltage: 3.25 V.
