SY10H607

Micrel, Inc. NOT RECOMMENDED FOR NEW DESIGNS REGISTERED HEX PECL-TO-TTL SY10H607 SY1S0YH10600H7607 SY100H607 FEATURES s Differential PECL data and clock inputs s 48mA sink, 15mA source TTL outputs s Single +5V power supply s Multiple power and ground pins to minimize noise s Specified within-device skew s VBB output for single-ended use s Fully compatible with MC10H/100H607 s Available in 28-pin PLCC package 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.
