Description
The GS9062 is a dual-standard serializer with an
integrated cable driver. When used in conjunction with
the GO1555/GO1525* Voltage Controlled Oscillator, a
transmit solution can be realized for 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 GS9062 can tolerate in excess of 300ps 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
GS9062’s PCLK input and configure the GS9062’s loop
bandwidth accordingly.
In addition to serializing the input, the GS9062 performs
NRZ-to-NRZI encoding and scrambling as per SMPTE
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. 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 and
adjustable signal swing.
The GS9062 also includes a range of data processing
functions including automatic standards detection and
EDH support. The device can also insert TRS signals,
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.
The GS9062 is Pb-free, and the encapsulation
compound does not contain halogenated flame
retardant (RoHS compliant).
