APPLICATIONS

Limited space, low power SMPTE 259M-C or generic
270Mb/s serial to parallel interfaces; DVB-ASI 270Mb/s
receive interface; broadcast quality uncompressed video
interface for industrial and professional video equipment
such as video editing workstations.

DESCRIPTION

The GS7005 is a BiCMOS integrated circuit capable of
operating as a complete 270Mb/s Serial Digital Video
receiver. The GS7005 provides a complete serial digital
video receive solution while consuming only 750mW.

The serial data input accepts SMPTE 259M-C compliant
signals. An on-chip by-passable equalizer typically pro­vides 100m of co-axial cable equalization. The clock
recovery is performed on chip with minimal external
components. The incoming serial data is decoded using an
NRZI decoder and SMPTE descrambler to provide SMPTE
125M compliant 27Mb/s parallel data outputs and clock.

NOTES

1. Rise/Fall time is defined as the time for the signal to rise from 20% to 80% of the specified p-p value, or to fall from 80% to 20% of the
specified value.

2. Refer also to Figure 10.

3. This is the time difference between the rising edge of PCLK

and the centre of the bit period.

OUT

4. This is the time delay between a valid serial TRS signal on the input to the moment valid data appears on the parallel outputs.

5. This is the time for the PLL to re-lock when video streams are switched during the vertical blanking interval in accordance with SMPTE
RP168-1993. The two streams may be 180° out of phase with respect to one another, but pixel aligned.

6. This pathological pattern is defined in SMPTE RP178-1996, paragraphs 4.1 and 4.3.

7. "Error free" is defined as no single bit errors over a period of 10 minutes, using Belden 8281 Cable and 75Ω connections. The MIN
value is fully tested and the TYP value is based on using the EB7005 Evaluation Board.
