3. Detailed Description
3.1 Functional Overview
The GS1560A/GS1561 is a dual-rate reclocking deserializer. An integrated serial
digital loop-through output is also included on the GS1560A only. When used in
conjunction with the multi-rate GS1524 Adaptive Cable Equalizer and the external
GO1525 Voltage Controlled Oscillator, a receive solution at 1.485Gb/s,
1.485/1.001Gb/s or 270Mb/s is realized.
The device has two basic modes of operation which determine precisely how
SMPTE or DVB-ASI compliant input data streams are reclocked and processed.
In master mode, (MASTER/SLAVE = HIGH), the GS1560A/GS1561 will
automatically detect, reclock, deserialize and process SD SMPTE 259M-C, HD
SMPTE 292M, or DVB-ASI input data.
In slave mode, (MASTER/SLAVE = LOW), the application layer must set external
device pins for the correct reception of either SMPTE or DVB-ASI data. Slave
mode also supports the reclocking and deserializing of data not conforming to
SMPTE or DVB-ASI streams.
The GS1560A includes an integrated cable driver is for serial input loop-through
applications. It can be selected to output either buffered or reclocked data. The
cable driver also features an output mute on loss of signal, high impedance mode,
adjustable signal swing, and automatic dual slew-rate selection depending on
HD/SD operational requirements.
In the digital signal processing core, several data processing functions are
implemented including error detection and correction and automatic video
standards detection. These features are all enabled by default, but may be
individually disabled via internal registers accessible through the GSPI host
interface.
Finally, the GS1560A/GS1561 contains a JTAG interface for boundary scan test
implementations.
