Registered Hex TTL/PECL

Translator

The MC10/100H606 is a 6–bit, registered, single supply TTL to PECL

translator. The device features differential PECL outputs as well as a choice

between either a differential PECL clock input or a TTL clock input. The

asynchronous master reset control is a PECL level input.

With its differential PECL outputs and TTL inputs the H606 device is

ideally suited for the transmit function of a HPPI bus type board–to–board

interface application. The on chip registers simplify the task of synchronizing

the data between the two boards.

The device is available in either ECL standard: the MECL

™ 10H device is

compatible with MECL 10KH logic levels, with a VCC of +5 volts; while the

100H device is compatible with 100K logic levels, with a VCC of +5 volts.

• Differential 50Ω ECL Outputs

• Choice Between Differential PECL or TTL Clock Input

• Single Power Supply

• Multiple Power and Ground Pins to Minimize Noise

1. When using PECL inputs, TCLK must be tied to ground (0V).

2. When using only one PECL input, the unused PECL input must be tied

to VBB, and TCLK must be tied to ground (0V).

3. When using TCLK, both PECL inputs must be tied to ground (0V).
