HMC959LC3 v02.0614 DIVIDE-BY-4 w/ RESET & PROGRAMMABLE OUTPUT VOLTAGE, 26 GHz Typical Applications Features t he HMc 959lc 3 is ideal for: Supports c lock Frequencies up to 26 g Hz High Speed Frequency Divider (up to 26 GHz) d ifferential or Single-ended o peration Broadband Test & Measurement Fast Rise and Fall t imes: 19 ps Clock Synthesis l ow power c onsumption: 281 mW typ. programmable d ifferential Phase Locked Loops o utput Voltage Swing: 800 - 1800 mVp-p propagation d elay: 121 ps Single Supply: -3.3 V 2 16 l ead c eramic 3x3 mm SMt p ackage: 9 mm Functional Diagram General Description t he HMc959lc 3 is a divide-by-4 w/Reset desig- ned to support clock frequencies as high as 26 g Hz. during normal operation, with the reset pin not asserted, the output toggles from its prior state on the positive edge of the clock. t his results in a divide-by- four function of the clock input. asserting the reset pin forces the Q output low regardless of the clock edge state (asynchronous reset assertion). Reversing the clock inputs allows for negative-edge triggered applications. all differential inputs to the HMc 959lc 3 are c Ml and terminated on-chip with 50 o hms to the positive supply, g Nd, and may be dc or ac coupled. o utputs can be connected directly to a 50 ohm ground-terminated system or drive devices with cMl logic input. the HMc 959lc 3 also features an output level control pin, VR, which allows for loss compensation or signal level optimization. t he HMc 959lc 3 operates from a single -3.3 V supply and is available in Ro HS-compliant 3x3 mm SMt package.
