Description
The GS2988 is a high-speed BiCMOS integrated circuit
designed to drive one to two 75Ω coaxial cables.
The GS2988 may drive data rates up to 2.97Gb/s and
provides two selectable slew rates in order to achieve
compliance to SMPTE 424M, SMPTE 292M and SMPTE
259M.
The GS2988 accepts industry-standard differential input
levels including LVPECL and CML.
Input trace equalization compensates for up to 10 inches of
FR4 trace loss while in HD and 3G modes. This feature can
be disabled using the EQ_EN pin.
The DISABLE pin powers-down the entire device.
The GS2988 features adjustable output swing using an
external bias resistor. The single-ended output swing is
adjustable from 500mVpp to 1800mVpp.
An output signal presence function, the OSP pin, indicates
whether an active signal is present at the output of the
GS2988.
The GS2988 can be powered from either a 3.3V or a 2.5V
supply. Power consumption is typically 110mW using a
2.5V power supply.
The GS2988 is Pb-free, and the encapsulation compound
does not contain halogenated flame retardant.
This component and all homogeneous subcomponents are
RoHS compliant.

4. Detailed Description
4.1 Serial Data Input
The GS2988 features a differential input buffer with on-chip 100Ω differential
termination.
The serial data input signal is connected to the DDI and DDI input pins of the device.
Input signals can be single-ended or differential, DC or AC-coupled.
The serial data input buffer is capable of operation with any binary coded signal that
meets the input signal level requirements, in the range of 270Mb/s to at least 2.97Gb/s.
The input circuit is self-biasing to allow for simple AC or DC-coupling of input signals to
the device.
4.2 Input Trace-equalization
The GS2988 features fixed trace-equalization to compensate for PCB trace dielectric
losses.
NOTE: This feature is not available in SD mode, and therefore trace-equalization must
be disabled when operating in this mode.
The trace-equalization has two settings, OFF and ON. ON invokes a typical 3dB gain
value at 1.5GHz. This value is optimized for compensating the high-frequency losses
associated with approximately 10 inches of 5-mil stripline in FR4 material.
4.3 Serial Data Output
The GS2988 features a current-mode differential output driver capable of driving up to
1800mVpp single-ended into a 1m length of 75Ω cable terminated at both ends.
The output signal amplitude or swing is user configurable using an external RSET
resistor.
The SDO/SDO pin of the device provide the serial data outputs.
4.3.1 Slew Rate Selection (Rise/Fall Time Requirement)
The GS2988 supports two user-selectable output slew rates.
Control of the slew rate is determined by the setting of the SD/HD input pin.

52131 - 4 December 2010

4.4 Output Disable
The GS2988 supports an output disable function for the serial data differential output.
Control of this function is determined by the setting of the DISABLE control pin.
The serial output disable (DISABLE), disables power to the entire device. When asserted
LOW, the SDO/SDO output driver is powered-down.
4.5 Output Signal Presence Indicator (OSP)
The GS2988 supports an output signal presence indicator function.
The output signal presence pin (OSP) is an active-low output that indicates when a valid
output signal has been detected at the pre-driver output.
The output signal presence function measures signal-edge energy to indicate that the
pre-driver to the serial data outputs is toggling.
4.6 Output Amplitude (RSET)
The output amplitude of the GS2988 can be adjusted by changing the value of the RSET
resistor as shown in Figure 4-1. For an 800mVp-p output with a nominal ±7% tolerance,
a value of 750Ω is required. A ±1% SMT resistor should be used.

The RSET resistor is part of an internal DC feedback loop in the GS2988. The resistor
should be placed as close as possible to the RSET pin, and connected directly to the VCC
plane (traces/wires may cause instability). In addition, the PCB capacitance should be
minimized at this node by removing the PCB groundplane beneath the RSET resistor and
the RSET pin.
NOTE: Care should be taken when considering layout of the RSET resistor. Please refer
to Section 5.1 for more details.
Figure 4-1: VOUT vs. RSET
In order to determine the best starting value for Rset, the following formula should be
used:
Rset = 8*(Rtrm/VoutppSE)
Where VoutppSE is in Volts, and both resistances are in Ω.
Rtrm is the value of the termination resistors, which should be equal to the
characteristic impedance of the cable, and is typically 75Ω.
The cable must be short (1m), and terminated at both ends for the formula to be valid.
Example: For a 75Ω cable, Rtrm = 75Ω (at both ends), VoutppSE = 800mV
Rset = 8*(75/0.8) = 750Ω

This formula is not valid for long, unterminated, or improperly terminated cables.
This formula should be considered as a starting point, and actual swing values may vary
based on layout. Also, for large output swings (>1040mV), smaller Rset values may be
required in order to achieve the desired output swing level at HD and 3G data rates.
4.7 Output Return Loss Measurement
The GS2988 has a feature which allows users to measure ORL reliably while the device
is still powered. The device can be put into a BALANCE mode which prevents the
outputs from toggling while the device is powered on, allowing the ORL to be measured
while the device is still powered.
When EQ_EN is LOW while SD/HD is HIGH, the device goes into BALANCE mode. This
mode is used during ORL measurement, disabling the AC signal path of the device
without powering it down. When in BALANCE mode, the device produces equal
pull-down currents in both differential shoulders of the serial data differential output,
effectively stopping the output at the output common mode voltage level. Gennum
recommends using BALANCE mode when measuring ORL with 2.5V termination
voltage.

*NOTE: In order to generate output swings greater than 1040mV, VCC_TERM must be
connected to a 5V supply.

5. Application Information
5.1 PCB Layout
Special attention must be paid to component layout when designing serial digital
interfaces for HDTV.
An FR-4 dielectric can be used, however, controlled impedance transmission lines are
required for PCB traces longer than approximately 1cm. Note the following PCB artwork
features used to optimize performance:
The PCB trace width for HD rate signals is closely matched to SMT component
width to minimize reflections due to changes in trace impedance
The PCB ground plane is removed under the GS2988 output components to
minimize parasitic capacitance (NOTE: care should be taken, as removing too much
of the plane will make the system susceptible to EMI)
The PCB ground plane is removed under the GS2988 RSET pin and resistor to
minimize parasitic capacitance. The RSET resistor should be directly connected to
the VCC plane
Input and output BNC connectors are surface mounted in-line to eliminate a
transmission line stub caused by a BNC mounting via high-speed traces
High-speed traces are curved to minimize impedance variations due to change of
PCB trace width
NOTE: For more recommendations on Trace Lengths, ORL Inductor Values and other
PCB Layout Considerations, please refer to Gennum’s GS2989 Design Guide
(Doc ID 52070).
