描述 Description

The MT90732 E2/E3 Framer (E2/E3F) is a CMOS VLSI device that provides the functions needed to frame a wideband payload to one of four CCITT Recommendations. G.742, G.745, G.751, or G.753. The E2/E3 Framer interfaces to line circuitry with either dual rail or NRZ signals. On the terminal side, the interface can be either nibble-parallel or bit-serial.
