REGISTERED HEX
TTL-TO-PECL
SY10H606
SY100H606
FEATURES
■ Differential 50Ω ECL outputs
■ Choice between differential PECL or TTL clock input
■ Single +5V power supply
■ VBB output for single-ended use
■ Multiple power and ground pins to minimize noise
■ Specified within-device skew
■ Fully compatible with Motorola MC10H/100H606
■ Available in 28-pin PLCC package
DESCRIPTION
The SY10/100H606 are 6-bit, registered, single supply
TTL-to-PECL translators. The devices feature 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 ECL 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
10H device is compatible with 10K logic levels, while the
100H device is compatible with 100K logic levels.
