Description
The GS1528A/9068A is a second generation
high-speed BiCMOS integrated circuit designed to drive
one or two 75Ω co-axial cables.
The GS1528A may drive data rates up to 1.485Gb/s
and provides two selectable slew rates in order to
achieve compliance to SMPTE 259M, SMPTE 344M
and SMPTE 292M.
The GS9068A may drive data rates up to 540Mb/s and
will achieve compliance to SMPTE 259M and SMPTE
344M.
The GS1528A/9068A accepts a LVPECL level
differential input that may be AC coupled. External
biasing resistors at the inputs are not required.
Power consumption is typically 168mW using a 3.3V
power supply.
The GS1528A/9068A is Pb-free, and the encapsulation
compound does not contain halogenated flame
retardant.
This component and all homogeneous subcomponents
are RoHS compliant.
Applications
GS1528A
• SMPTE 292M, SMPTE 344M and SMPTE 259M
Coaxial Cable Serial Digital Interfaces.
GS9068A
• SMPTE 259M and SMPTE 344M Coaxial Cable

5.3 Output Return Loss Measurement
To perform a practical return loss measurement, it is necessary to force the
GS1528A/9068A output to a DC high or low condition. The actual measured return
loss will be based on the outputs being static at VCC or VCC-1.6V. Under normal
operating conditions the outputs of the device swing between VCC-0.4V and
VCC-1.2V, so the measured value of return loss will not represent the actual
operating return loss.
A simple method of calculating the values of actual operating return loss is to
interpolate the two return loss measurements. In this way, the values of return loss
are estimated at VCC-0.4V and VCC-1.2V based on the measurements at VCC and
VCC-1.6V.
The two values of return loss (high and low) will typically differ by several decibels.
If the measured return loss is RH for logic high and RL for logic low, then the two
values can be interpolated as follows:
RIH = RH- (RH-RL)/4 and
RIL = RL+(RH-RL)/4
where RIH is the interpolated logic high value and RIL is the interpolated logic low
value.
For example, if RH = -18dB and RL = -14dB, then the interpolated values are
RIH = -17dB and RIL = -15dB.
