5 VꢀECL 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.
