MC10EP445, MC100EP445
3.3V/5V ECL 8−Bit
Serial/Parallel Converter
The MC10/100EP445 is an integrated 8–bit differential serial to
parallel data converter with asynchronous data synchronization. The
device has two modes of operation. CKSEL HIGH mode is designed
to operate NRZ data rates of up to 3.3 Gb/s, while CKSEL LOW mode
is designed to operate at twice the internal clock data rate of up to
5.0 Gb/s. The conversion sequence was chosen to convert the first
serial bit to Q0, the second bit to Q1, etc. Two selectable differential
serial inputs, which are selected by SINSEL, provide this device with
loop-back testing capability. The MC10/100EP445 has a SYNC pin
which, when held high for at least two consecutive clock cycles, will
swallow one bit of data shifting the start of the conversion data from
D
n
to D
n+1
. Each additional shift requires an additional pulse to be
applied to the SYNC pin.
Control pins are provided to reset and disable internal clock
circuitry. Additionally, V
BB
pin is provided for single-ended input
condition.
The 100 Series contains temperature compensation.
