Octal E1 Transceiver Chip |
| OVERVIEW |
| Octal E1 Transceiver CP5028 is one of the ETLINK series chips designed by Chiphomer Technology Company, it integrates eight independent E1 transceivers into a single chip. Each E1 transceiver works functionally as CP5021, which provide complete function of E1 line interface and E1 Framer. |
