Sunnyvale, Calif. The DS3146 six-channel, DS3148 eight-channel, and DS31412 twelve-channel framers have been unleashed for T3/E3 applications. Packaged in a 27-mm plastic BGA, the framers interface to a variety of line interface units (LIUs), microprocessor buses, and other system components without glue logic. Each framer has its own HDLC controller, FEAC controller, and BERT while providing support for error detection, error generation, performance monitoring, and loopbacks. The framers also sport framing and formatting to M23 DS3, C-bit parity D-3, and G.751 E3; an NRZ or dual-rail LIU interface; an optional B2ZS/HDB3 encoder and decoder; per-channel power down; and an 8-bit microprocessor interface.
All of the devices operate from a 3.3-V supply and offer 5-V tolerant I/Os. They are supplied in commercial and industrial temperature grades.
Pricing: Starts at $14.36 for industrial temperature parts
