HD-LINX ™ GS1540
HDTV Serial Digital
Non-Equalizing Receiver
DATA SHEET
DESCRIPTION
• SMPTE 292M compliant
The GS1540 is a high performance integrated Receiver
designed for HDTV component signals, conforming to the
SMPTE 292M standard. The GS1540 includes adjustmentfree clock and data recovery, and 1:20 serial to parallel
conversion.
• 1.485 and 1.485/1.001Gb/s operation
• integrated adjustment-free reclocker
• 1:20 serial to parallel conversion
• selectable reclocked serial output
The Clock and Data Recovery stage was designed to automatically 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 buffer output and the ability to bypass the reclocker stage.
• reclocker BYPASS capability
• LOCK detect
• input jitter indicator (IJI)
• 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
• single +5.0V power supply
• minimal component count for HD SDI receive
solutions
The Serial to Parallel conversion stage provides 1:20 S/P
conversion.
APPLICATIONS
The GS1540 uses the GO1515 external VCO connected to
the internal PLL circuitry to achieve ultra low noise PLL
performance.
SMPTE 292M Serial Digital Interfaces for Production
Switchers, Master Control Switchers, NLE's, and VTR's.
