HD-LINX GS1545  
HDTV Serial Digital  
Equalizing Receiver  
DATA SHEET  
FEATURES  
DESCRIPTION  
• SMPTE 292M compliant  
• 1.485 and 1.485/1.001Gb/s operation  
• integrated adaptive cable equalizer  
• integrated adjustment-free reclocker  
• 1:20 serial to parallel conversion  
• selectable reclocked serial output  
• analog/digital input MUX  
• carrier detect  
The GS1545 is a high performance integrated Equalizing  
Receiver designed for HDTV component signals,  
conforming to the SMPTE 292M standard. The GS1545  
includes adjustment free adaptive cable equalization, clock  
and data recovery, and serial to parallel conversion.  
The Equalizer stage features DC restoration for immunity to  
the DC content in pathological test patterns.  
The Clock and Data Recovery stage was designed to auto-  
matically recover the embedded clock signal and re-time  
the data from SMPTE 292M compliant digital video signals.  
There is also a selectable reclocked serial data output and  
the ability to bypass the reclocker stage.  
• LOCK detect  
• input jitter indicator (IJI)  
• cable length indication  
• maximum cable length adjust  
• 20 bit output  
A unique feature, Input Jitter Indicator (IJI), is included for  
robust system design. This feature is used to indicate  
excessive input jitter before the chip mutes the outputs.  
• 74.25MHz or 74.25/1.001MHz clock output  
• Pb-free and Green  
The Serial to Parallel conversion stage provides 1:20 S/P  
conversion  
• single +5.0V power supply  
The GS1545 uses the GO1515 external VCO connected to  
the internal PLL circuitry to achieve ultra low noise PLL  
performance.  
• minimal component count for HD SDI receive  
solutions  
APPLICATIONS  
SMPTE 292M Serial Digital Interfaces for Video Cameras,  
Camcorders, VTRs, Signal Generators, Portable Equipment,  
and NLEs.
