HMC750LP4e also features an output level control pin, vc1, which allows for loss compensation or for signal level optimization. differential output signal swing can be adjustable up to 880mv p-p. input signals higher than 3mv p-p can be amplifi ed to saturated 880mv p-p differential signal. all single-ended input signals to the HMC750LP4e are terminated with 50 ohms to +5v on-chip, and may be either ac or dc coupled. the outputs of the HMC750LP4e may be operated either differentially or single-ended. outputs can be connected directly to a 50 ohm terminated system referenced to +5v, while dc blocking capacitors may be used if the terminating system is 50 ohms to a non +5v voltage. the HMC750LP4e operates from a single + 5v dc supply and is available in a plastic rohs compliant 4x4 mm smt package. parameter conditions min. typ. max. units power supply voltage 4.6 5 5.4 v power supply current vc1 = 2.5v 106 122 ma maximum data rate 12.5 gbps differential small signal gain vc1 = 2.5v 44 db small signal bandwidth 3-db cutoff 11 ghz deterministic jitter [1] vin = 20 mv peak to peak 5 ps p-p additive random jitter [2] vin = 200 mv peak to peak 0.2 ps rms typical applications features general description 12.5 gbps limiting amplifier
