Functional Diagram

General Description

The HMC874LC3C is a SiGe monolithic, ultra fast

comparator which features reduced swing PECL

output drivers and clock inputs. The comparator

supports 20 Gbps operation while providing 120 ps

clock to data output delay and 60 ps minimum pulse

width with 0.2 ps rms random jitter (RJ). 25 Gbps

operation can be achieved with reduced output vol-

tage swing. Overdrive and slew rate dispersion are

typically 10 ps, making the device ideal for a wide

range of applications from ATE to broadband com-

munications. The reduced swing PECL output stages

are designed to directly drive 400 mV into 50 Ohms

terminated to +1.3V while maintaining compatibility

with other PECL logic families. The HMC874LC3C

features high speed latches with programmable

hysteresis, and is conﬁgured to operate as a clocked

comparator.

Electrical Speciﬁcations T_A= +25C,

Vcci= +3.3V, Vcco = +3.3V, CLK / CLK = 1.6 to 2.4V, Vee = -3V, V_TERM= +1.3V
