DESCRIPTION
The SY10/100H607 are 6-bit, registered, dual supply
PECL-to-TTL translators. The devices feature differential
PECL inputs for both data and clock. The TTL outputs
feature 48mA sink, 15mA source drive capability for
driving high fanout loads. The asynchronous master reset
control is a PECL level input.
With its differential PECL inputs and TTL outputs, the
H607 device is ideally suited for the receive 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
10H device is compatible with 10K logic levels, while the
100H device is compatible with 100K logic levels.
