GENLINX ™II GS9035A
Serial Digital Reclocker
DATA SHEET
DESCRIPTION
• adjustment-free operation
The GS9035A is a high performance clock and data
recovery IC designed for serial digital data. The GS9035A
receives either single-ended or differential PECL data and
outputs differential PECL clock and retimed data signals.
• auto-rate selection for 5 SMPTE data rates: 143, 177,
270, 360, 540Mb/s
• data rate indication output
The GS9035A can operate in either auto or manual rate
selection mode. In auto mode the GS9035A is ideal for
multi-rate serial data protocols such as SMPTE 259M. In this
mode the GS9035A automatically detects and locks onto
the incoming data signal. For single rate data systems, the
GS9035A can be configured to operate in manual mode. In
both modes, the GS9035A requires only one external
resistor to set the VCO centre frequency and provides
adjustment-free operation.
• serial data output mute when PLL is not locked
• immune to harmonic locking
• operation independent of SAV/EAV sync signals
• low jitter, low power
• single external VCO resistor for operation with five
input data rates
• large input jitter tolerance: typically 0.45 UI beyond
loop bandwidth
• power savings mode (output serial clock disable)
The GS9035A has dedicated pins to indicate LOCK and
data rate. In addition, an internal muting function forces the
serial data outputs to a static state when input data is not
present or when the PLL is not locked. The serial clock
outputs can also be disabled resulting in a 10% power
savings.
• system friendly: serial clock remains active when data
outputs muted
• robust lock detect
• Pb-free and Green
APPLICATIONS
The GS9035A is packaged in a 28 pin PLCC and operates
from a single +5 or -5 volt power supply.
The GS9035A is used for Clock and Data recovery, and
Jitter elimination for all high speed serial digital interface
applications involving SMPTE 259M and other data
standards.
