The HMC676LC3C is a SiGe monolithic, ultra fast

comparator that features reduced swing (RS) ECL

output drivers and latch inputs. The comparator

supports 10 Gbps operation while providing 100 ps

propagation delay and 60 ps minimum pulse width with

0.2 ps rms random jitter (RJ). Overdrive and slew rate

dispersion are typically 10 ps, making the device ideal

for a wide range of applications from ATE to broadband

communications. The reduced swing ECL output stage

is designed to directly drive 400 mV into 50 ohms

terminated to -2 V. The HMC676LC3C features high

speed latch and programmable hysteresis and may

be configured to operate in either latch mode, or as a

tracking comparator.

10 GHz LATCHED COMPARATOR

WITH RSECL OUTPUT STAGE

Operational Description

COMPARATORS - SMT

The HMC676LC3C is a Latched Comparator with 10 GHz equivalent input bandwidth. The device is comprised of three

blocks: 1) An input amplifier, 2) A latch, and 3) An RSECL Output Buffer. The latching circuit is level sensitive, and

consists of a single high-speed latch. The HMC676LC3C comparator supports 10 Gb/s operation. The minimum input

data latching pulse width is 60 ps.

The HMC676LC3C operates in either Track (Transparent) Mode, where the output follows the logical value of the input,

or the Latch (Hold) Mode, where the output value is held to the logical value of the comparison result of the input just prior

to (LE - LE_bar) going HI. Track Mode operation is selected by either 1) (LE - LE_bar) LO, or 2) LE and LE_bar inputs

floating. Latch Mode is selected by (LE - LE_bar) HI. The input impedance of the LE and LE_bar inputs is 8 k ohms, but

these inputs can be terminated with 50 ohm external resistors if desired.

When DC coupled, the clock inputs operate at an input common mode voltage of 2 V. In this case, any termination

resistors would ideally be returned to 2 V. If the clock is AC coupled to the device, the input termination resistors can be

returned to ground.
