3. Detailed Description

3.1 Functional Overview

The GS9062 is a dual-standard serializer with an integrated cable driver. When

used in conjunction with the external GO1555/GO1525* Voltage Controlled

Oscillator, a transmit solution at 270Mb/s is realized.

The device has three different modes of operation which must be set by the

application layer through external device pins.

When SMPTE mode is enabled, the device will accept 10-bit multiplexed or 20-bit

demultiplexed SMPTE compliant data. The device’s additional processing features

are also enabled in this mode.

In DVB-ASI mode, the GS9062 will accept an 8-bit parallel DVB-ASI compliant

transport stream on its upper input bus. The serial output data stream will be

8b/10b encoded and stuffed.

The GS9062’s third mode allows for the serializing of data not conforming to

SMPTE or DVB-ASI streams.

The provided serial digital outputs feature a high impedance mode, output mute on

loss of parallel clock and adjustable signal swing.

In the digital signal processing core, several data processing functions are

implemented including SMPTE 352M and EDH data packet generation and

insertion, 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 GS9062 contains a JTAG interface for boundary scan test

implementations.

*For new designs use GO1555

3.2 Parallel Data Inputs

Data inputs enter the device on the rising edge of PCLK as shown in Figure 3-1.

The input data format is defined by the setting of the external SMPTE_BYPASS

and DVB_ASI pins and may be presented in 10-bit or 20-bit format. The input data

bus width is controlled independently from the internal data bus width by the

20bit/10bit input pin.
