HDTV Serial Digital Formatter

with ANC FIFOs

DATA SHEET

KEY FEATURES

DESCRIPTION

• SMPTE 292M compliant

• NRZ(I) encoding

The GS1501 HDTV Serial Digital Formatter formats the

HDTV Luma and Chroma data according to SMPTE 292M

prior to serialization by the GS1522 HDTV Serializer. The

GS1501 optionally inserts TRS and line number signals

based on externally supplied H, V and F signals. The

device also allows the insertion of CRCs based on TRS

signals embedded in the input data streams, should the

user choose not to supply external HVF signals.

• SMPTE 292M scrambler with BYPASS option

• internal FIFOs for ANC data insertion

(1024 Bytes on Y and C channels)

• selectable TRS insertion

• selectable line number insertion

• selectable line based CRC insertion

• selectable active picture illegal code re-mapping

• 20 bit 3.3V CMOS compatible input data bus

• optimized output interface to GS1522

• single +3.3V power supply

Following the insertion of TRS, Line Number, and CRC,

protected words of 000-003 and 3FC to 3FF occurring

during the active video period are optionally re-mapped to

004 and 3FB respectively. In addition, ANC data may be

inserted into the video stream through an internal FIFO

interface. Prior to exiting the device SMPTE 292M compliant

NRZ(I) encoding and scrambling may be performed on the

data stream.

• 5V tolerant I/O
