GS1582  
Multi-Rate Serializer with Cable Driver,  
Audio Multiplexer and ClockCleaner™  
GS1582 Data Sheet  
Key Features  
Description  
•
HD-SDI, SD-SDI, DVB-ASI transmitter with audio  
embedding  
The GS1582 is the next generation multi-standard  
serializer with an integrated cable driver. The device  
provides robust parallel to serial conversion, generating  
a SMPTE 292M/259M-C compliant serial digital output  
signal. The integrated cable driver features an output  
disable (high impedance) mode and an adjustable  
signal swing. Data input is accepted in 20-bit parallel  
format or 10-bit parallel format. An associated parallel  
clock input must be provided at the appropriate  
operating frequency; 74.25/74.1758/13.5MHz (20-bit  
mode) or 148.5/148.352/27MHz (10-bit mode).  
•
Integrated SMPTE 292M and 259M-C compliant  
cable driver  
™
•
•
Integrated ClockCleaner  
User selectable video processing features,  
including:  
•
Generic ancillary data insertion  
•
•
•
Support for HVF or EIA/CEA-861 timing input  
Automatic standard detection and indication  
The GS1582 features an internal PLL which, if desired,  
can be configured for a loop bandwidth below 100kHz.  
When used in conjunction with the GO1555 Voltage  
Controlled Oscillator, the GS1582 can tolerate well in  
excess of 300ps jitter on the input PCLK and still  
provide output jitter within SMPTE specifications.  
Enhanced SMPTE 352M payload identifier  
generation and insertion  
•
TRS, CRC, ANC data checksum, and line  
number calculation and insertion  
•
•
•
EDH packet generation and insertion  
Illegal code remapping  
In addition to serializing the input, the GS1582 performs  
NRZ-to-NRZI encoding and scrambling as per SMPTE  
292M/259M-C when operating in SMPTE mode. When  
operating in DVB-ASI mode, the device will insert K28.5  
sync characters and 8b/10b encode the data prior to  
serialization. The device also provides a range of other  
data processing functions. All processing features are  
optional and may be enabled/disabled via external  
control pin(s) and/or host interface programming.  
SMPTE 292M and SMPTE 259M-C compliant  
scrambling and NRZ → NRZI encoding  
•
Blanking of input HANC and VANC space  
•
User selectable audio processing features,  
including:  
•
SMPTE 299M and SMPTE 272M-A/C compliant  
audio embedding  
•
•
Support for up to 8 channels  
The GS1582 can embed up to 8 channels of audio into  
the video data stream in accordance with SMPTE 299M  
and SMPTE 272M. The audio input signal formats  
Support for audio group replacement  
•

•
JTAG test interface

supported by the device include AES/EBU and I S  
1.8V core and 3.3V charge pump power supply  
1.8V and 3.3V digital I/O support  
Low power standby mode  
serial digital formats with a 16, 20 or 24 bit sample size  
and a 48 kHz sample rate. Additional audio processing  
features include individual channel enable, channel  
swap, group swap, ECC generation and audio channel  
status insertion.

Operating temperature range: -20 C to +85 C  
Pb-free, RoHS compliant, 11mm x 11mm 100-ball  
BGA package  
Typical power consumption, including the GO1555  
VCO, is 500mW. The standby feature allows the power  
to be reduced to 125mW. Power may be reduced to less  
than 10mW by also removing the power to the cable  
driver and eliminating transitions at the parallel data and  
clock inputs.  
Applications  
•
SMPTE 292M and SMPTE 259M-C Serial Digital  
Interfaces  
•
DVB-ASI Serial Digital Interfaces  
The GS1582 is Pb-free and RoHS compliant.
