Description
The GS3140 is a high-speed BiCMOS device designed to
equalize and restore signals received over cable.
The device is designed to support SMPTE ST 424, SMPTE ST
292, SMPTE ST 259 and AES10 (MADI), and it is optimized
for performance at 125Mb/s, 270Mb/s, 1.485Gb/s, and
2.97Gb/s.
The device supports MADI serial signals at 125Mb/s with
peak-to-peak launch amplitude between 300mVppd and
600mVppd (with AES10 spec rise and fall times) and
800mVppd±10% (with SD-SDI rise and fall times).
The GS3140 features DC restoration to compensate for the
DC content of SMPTE pathological signals.
Loss of Signal (LOS) is detected when the input carrier is lost
or signal amplitude falls below a programmable threshold.
This is further processed by a filter programmable up to
1.6s before LOS status is asserted. The device can be
programmed to automatically sleep/mute/disable the
output on loss of signal.
An interrupt pin (INT) indicates LOS by default, and can be
programmed to signal various other statuses.
When the BYPASS control bit is set, the equalizing and DC
restore stages are disengaged. This is useful for signals
launched at the source with low data rates and/or slow rise
and fall times.

The differential output can be DC-coupled to Semtech’s
reclockers and cable drivers, as well as industry-standard
+1.2V, +1.8V and +2.5V CML logic by changing the voltage
applied to the VCC_O pin.
The GS3140 also features programmable output
de-emphasis with eight user-selectable operating levels to
support long PCB traces at the output of the device. The
output swing can be programmed, via the user interface,
from approximately 250mVppd to 1Vppd in 50mVppd steps.
The device comes in a 16-pin, 4mm x 4mm QFN–COL
package.
Power consumption of the GS3140 is typically 84mW when
DC-coupled to a +1.2V termination voltage with
OUTPUT_SWING = 0011b (see Table 4-2).
The GS3140 is Pb-free, and the encapsulation compound
does not contain halogenated flame retardant.
This component and all homogeneous subcomponents are
RoHS compliant.
