Multi-Rate SDI
Dual Slew-Rate Cable Driver
GS1528 Data Sheet
Description
The GS1528 is a second generation high-speed bipolar
integrated circuit designed to drive one or two 75Ω
co-axial cables at data rates up to 1.485Gb/s. The
GS1528 provides two selectable slew rates in order to
achieve compliance to SMPTE 259M, SMPTE 344M
and SMPTE 292M.
The GS1528 accepts a LVPECL level differential input
that may be AC coupled. External biasing resistors at
the inputs are not required.
Power consumption is typically 160mW using a 3.3V
power supply.
This component and all homogeneous subcomponents
are ROHS compliant.

4. Application Information
GS1528 Data Sheet
4.1 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 groundplane is removed under the GS1528 output components to
minimize parasitic capacitance.
The PCB ground plane is removed under the GS1528 RSET pin and resistor to
minimize parasitic capacitance.
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 which are
curved to minimize impedance variations due to change of PCB trace width.
