Applications Information
The MC10E/100E446 is an integrated 4:1 parallel to serial
converter. The chip is designed to work with the E445 device
to provide both transmission and receiving of a high speed
serial data path. The E446 can convert 4 bits of data into a
1.3Gb/s NRZ data stream. The device features a SYNC input
which allows the user to reset the internal clock circuitry and
restart the conversion sequence (see timing diagram A).
The E446 features a differential serial input and internal
divide by 8 circuitry to facilitate the cascading of two devices
to build a 8:1 multiplexer. Figure 1 illustrates the architecture
for a 8:1 multiplexer using two E446’s; the timing diagram for
this configuration can be found on the following page. Notice
the serial outputs (SOUT) of the lower order converter feed
the serial inputs of the the higher order device. This feed
through of the serial inputs bounds the upper end of the
frequency of operation. The clock to serial output
propagation delay plus the setup time of the serial input pins
must fit into a single clock period for the cascade architecture
to function properly. Using the worst case values for these
two parameters from the data sheet, TPD CLK to SOUT =
1480ps and tS for SIN = –200ps, yields a minimum period of
1280ps or a clock frequency of 780MHz.
The clock frequency is somewhat lower than that of a
single converter, to increase this frequency some games can
be played with the clock input of the higher order E446. By
delaying the clock feeding E446A relative to the clock of
E446B the frequency of operation can be increased.
