Description

Electronic Component Model: CX28380-16R is a part of the IC Chips category. It is a Dual/Triple/Quad/Hex/Octal-Enhanced DS3/E3 Framer manufactured by Conexant. This component is designed to support DS3-M13, DS3-C-bit parity, E3-G.751, and E3-G.832 transmission formats. It provides framing recovery for M13, M23, C-bit parity, G.751, and G.832 formatted signals. The CX28380-16R allows for ease of configuration and provides maximum flexibility to support the transmission and recovery of industry standard formats. It also features a flexible overhead bit generation method in DS3/E3 modes to source overhead bits on an individual framer. Power supplies required for this component are 3.3V and 2.5V, with an optional 5V supply for 5V input tolerance. It operates at low power consumption, drawing less than 200mW per port.
