Description
http://onsemi.com
The MC10/100EP446 is an integrated 8−bit parallel to serial data
converter. The device is designed with unique circuit topology to
operate for NRZ data rates up to 3.2 Gb/s. The conversion sequence
from parallel data into a serial data stream is from bit D0 to D7. The
parallel input pins D0−D7 are configurable to be threshold controlled by
CMOS, ECL, or TTL level signals. The serial data rate output can be
selected at internal clock data rate or twice the internal clock data rate
using the CKSEL pin.
Control pins are provided to reset (SYNC) and disable internal clock
circuitry (CKEN). In either CKSEL modes, the internal flip−flops are
triggered on the rising edge for CLK and the multiplexers are switched
on the falling edge of CLK, therefore, all associated specification
limits are referenced to the negative edge of the clock input.
