The GS9035C is a high performance clock and data recovery IC designed for serial digital data. The GS9035C receives either single-ended or differential PECL data and outputs differential PECL clock and retimed data signals.
The GS9035C can operate in either auto or manual rate selection mode. In auto mode the GS9035C is ideal for multi-rate serial data protocols such as SMPTE 259M. In this mode the GS9035C automatically detects and locks onto the incoming data signal. For single rate data systems, the GS9035C can be configured to operate in manual mode. In both modes, the GS9035C requires only one external resistor to set the VCO centre frequency and provides adjustment-free operation.
The GS9035C 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.
The GS9035C is packaged in a 28 pin PLCC and operates from a single +5 or -5 volt power supply.
- adjustment-free operation
- auto-rate selection for 4 SMPTE data rates: 143, 177, 270, 360Mb/s
- data rate indication output
- serial data output mute when PLL is not locked
- operation independent of SAV/EAV sync signals
- low jitter, low power
- single external VCO resistor for operation with four input data rates
- large input jitter tolerance: typically 0.50 UI beyond loop bandwidth at 270Mb/s
- power savings mode (output serial clock disable)
- system friendly: serial clock remains active when data outputs muted
- robust lock detect
The GS9035C 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.
