Description
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).
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.
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.
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
supported by the device include AES/EBU and I
2
S
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.
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.
The GS1582 is Pb-free and RoHS compliant.
