5 VECL 8-Bit Ripple Counter
Description
The MC10E/100E137 is a very high speed binary ripple counter. The
two least significant bits were designed with very fast edge rates while
the more significant bits maintain standard ECLinPS output edge
rates. This allows the counter to operate at very high frequencies while
maintaining a moderate power dissipation level.
The device is ideally suited for multiple frequency clock generation
as well as a counter in a high performance ATE time measurement
board.
Both asynchronous and synchronous enables are available to
maximize the device’s flexibility for various applications. The
asynchronous enable input, A_Start, when asserted enables the counter
while overriding any synchronous enable signals. The E137 features
XORed enable inputs, EN1 and EN2, which are synchronous to the
CLK input. When only one synchronous enable is asserted the counter
becomes disabled on the next CLK transition; all outputs remain in the
previous state poised for the other synchronous enable or A_Start to be
asserted to re-enable the counter. Asserting both synchronous enables
causes the counter to become enabled on the next transition of the CLK.
If EN1 (or EN2) and CLK edges are coincident, sufficient delay has
been inserted in the CLK path (to compensate for the XOR gate delay
and the internal D-flip flop setup time) to insure that the synchronous
enable signal is clocked correctly, hence, the counter is disabled.
All input pins left open will be pulled LOW via an input pulldown
resistor. Therefore, do not leave the differential CLK inputs open.
Doing so causes the current source transistor of the input clock gate to
become saturated, thus upsetting the internal bias regulators and
jeopardizing the stability of the device.
The asynchronous Master Reset resets the counter to an all zero state
upon assertion.
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.
