GS1510-CQR中文资料根努姆数据手册PDF规格书

DESCRIPTION

When interfaced to the Gennum GS1545 HDTV Equalizing Receiver or GS1540 Non-Equalizing Receiver, the GS1510 performs the final conversion to word aligned data. The device performs NRZI decoding and de-scrambling as per SMPTE 292M and word-aligns to the incoming data stream. Line based CRCs are calculated on the incoming data stream and are compared against the CRCs embedded within the data stream.

FEATURES

• SMPTE 292M compliant

• standards detection/indication for SMPTE 292M levels A/B,C,D/E,F,G/H,I,J/K,L/M

• NRZI decoding and SMPTE descrambling with BYPASS option

• line CRC calculation, comparison

• selectable line based CRC re-Insertion

• H, V, F timing reference signal (TRS) extraction

• selectable flywheel for noise immune H, V, F extraction

• selectable automatic switch line handling

• selectable TRS and line number re-insertion

• selectable active picture illegal code re-mapping

• configurable FIFO LOAD pulse

• 20 bit 3.3V CMOS input data bus

• optimized input interface to GS1545 or GS1540

• single +3.3V power supply

• 5V tolerant I/O
