3.3V/5V 8-Bit
CMOS/ECL/TTL Data Input
Parallel/Serial Converter
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.

MARKING DIAGRAM*
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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

The device also features a differential SYNC input (Pins 29 and 30), which asynchronously reset all internal flip–flops and
clock circuitry on the rising edge of SYNC. The release of SYNC is a synchronous process, which ensures that no runt serial
data bits are generated. The falling edge of the SYNC followed by a falling edge of CLK initiates the start of the conversion
process on the next rising edge of CLK (Figures 8 and 9). As shown in the figures below, the device will start to latch the parallel
input data after the a falling edge of SYNC ¬, followed by the falling edge CLK , on the next rising of edge of CLK ® for

The differential synchronous CKEN inputs (Pins 6 and 7), disable the internal clock circuitry. The synchronous CKEN will
suspend all of the device activities and prevent runt pulses from being generated. The rising edge of CKEN followed by the
