Operates at 2-bit Non-Return to Zero (NRZ) Data Rates up to 50 Mbits second Single a 5V Power Supply Operation Low Power Dissipation when TTL .
This is accommplished by the setting of a bit in the control register The ENDEC also includes write data precompensation.
The DP84902 is designed to perform the encoding and decoding for disk memory systems It is designed to interface directly with Integrated Read Channel Products (such as National Semiconductor’s DP84910) and with Disk Data Controller Products with a 2.
