FEATURES
DTCP content protection (TSB42AA4 only). A separate document explains the DTCP hardware errata for TSB42AA4. It is available upon request to DTLA licensees only.
Interfaces directly to industry standard 400-, 200-, and 100-Mbps physical layer devices, including Texas Instruments TSB41LV0X and TSB41AXX family of physical layer devices
Compliant with IEEE 1394-1995 and IEEE 1394a–2000 standards
MPEG2 time stamp-based release, as described in IEC 61883-4
High-speed data interface (HSDI): – Byte-wide or serial mode
– Two independent HSDI ports
– Bidirectional
– Several control modes for a variety of applications
– Connects seamlessly to common MPEG2 decoder chipsets
16-bit microprocessor interface supports Motorola 68000/68020-style bus
Large 8K-byte FIFO can be configured up to eight independent Tx or Rx FIFOs
8K-byte FIFO supports the following data types:
