3.2 Serial Digital Input
The GS9090A contains a current mode differential serial digital input buffer. The
input buffer has internal 50
Ω
termination resistors, which are connected to ground
via the TERM pin.
If the input signal is AC coupled to the device, the signal source common mode
level will be set internally to typically 1.45V. If the input signal is DC coupled to the
device, the internal biasing will be ignored. Please see
AC Electrical
Characteristics on page 13
for Common Mode range and swing characteristics.
3.3 Clock and Data Recovery
The GS9090A contains an integrated clock and data recovery block. The function
of this block is to lock to the input data stream, extract a clean clock, and retime the
serial digital data to remove high frequency jitter.
3.3.1 Internal VCO and Phase Detector
The GS9090A uses an internal VCO and PFD as part of the internal clock and data
recovery block's phase-locked loop. Each block requires a +1.8V DC power
supply, which is supplied via the VCO_VDD / VCO_GND and PLL_VDD /
PLL_GND pins.
3.4 Serial-To-Parallel Conversion
The retimed data and phase-locked clock signals from the internal clock and data
recovery block are fed to the serial-to-parallel converter. The function of this block
is to extract 10-bit parallel data words from the reclocked serial data stream and
simultaneously present them to the SMPTE and DVB-ASI word alignment blocks.
3.5 Modes Of Operation
The GS9090A has two basic modes of operation: Auto mode and Manual mode.
Auto mode is enabled when the application layer sets the AUTO/MAN pin HIGH,
and Manual mode is enabled when the AUTO/MAN pin is set LOW. As indicated
in
Figure 3-1
, each mode supports both SMPTE and DVB-ASI input signals. In
addition, Data-Through functionality is possible when the GS9090A is in Manual
mode.
