Multi-Rate Serializer
GS1531 Data Sheet
Description
The GS1531 is a multi-standard serializer with an
integrated cable driver. When used in conjunction with
the GO1525 Voltage Controlled Oscillator, a transmit
solution can be realized for HD-SDI, SD-SDI and
DVB-ASI applications.
The device features an internal PLL, which can be
configured for loop bandwidth as narrow as 100kHz.
Thus the GS1531 can tolerate substantive jitter on the
input PCLK and still provide output jitter well within
SMPTE specification. Connect the output clocks from
Gennum’s GS4911 clock generator directly to the
GS1531’s PCLK input and configure the GS1531’s loop
bandwidth accordingly.
In addition to serializing the input, the GS1531 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.
Parallel data inputs are provided for 10-bit multiplexed
or 20-bit demultiplexed formats at both HD and SD
signal rates. An appropriate parallel clock input signal is
also required.
The integrated cable driver features an output mute on
loss of parallel clock, high impedance mode, adjustable
signal swing, and automatic dual slew rate selection
depending on HD/SD operational requirements.
The GS1531 also includes a range of data processing
functions including automatic standards detection and
EDH support. The device can also insert TRS signals,
calculate and insert line numbers and CRC’s, re-map
illegal code words and insert SMPTE 352M payload
identifier packets. All processing features are optional
and may be enabled/disabled via external control pin(s)
and/or host interface programming.
