5VECL 4-Bit Serial/Parallel
Converter
Description
The MC10/100E445 is an integrated 4-bit serial to parallel data
converter. The device is designed to operate for NRZ data rates of up to
2.0 Gb/s. The chip generates a divide by 4 and a divide by 8 clock for
both 4-bit conversion and a two chip 8-bit conversion function. The
conversion sequence was chosen to convert the first serial bit to Q0, the
second to Q1 etc.
Two selectable serial inputs provide a loopback capability for testing
purposes when the device is used in conjunction with the E446 parallel to
serial converter.
The start bit for conversion can be moved using the SYNC input. A
single pulse applied asynchronously for at least two input clock cycles
shifts the start bit for conversion from Qn to Qn1. For each additional
shift required an additional pulse must be applied to the SYNC input.
Asserting the SYNC input will force the internal clock dividers to
“swallow” a clock pulse, effectively shifting a bit from the Qn to the Qn1
output (see Timing Diagram B).
The MODE input is used to select the conversion mode of the device.
With the MODE input LOW, or open, the device will function as a 4-bit
converter. When the mode input is driven HIGH the data on the output will
change on every eighth clock cycle thus allowing for an 8-bit conversion
scheme using two E445’s. When cascaded in an 8-bit conversion scheme
the devices will not operate at the 2.0 Gb/s data rate of a single device.
Refer to the applications section of this data sheet for more information on
cascading the E445.
Upon power-up the internal flip-flops will attain a random state. To
synchronize multiple E445’s in a system the master reset must be asserted.
The VBB pin, an internally generated voltage supply, is available to this
device only. For single-ended input conditions, the unused differential
input is connected to VBB as a switching reference voltage. VBB may also
rebias AC coupled inputs. When used, decouple VBB and VCC via a
0.01
mF capacitor and limit current sourcing or sinking to 0.5 mA. When
not used, VBB should be left open.
The 100 Series contains temperature compensation.
