FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The 3D7522 product family consists of monolithic CMOS Manchester

Decoders. The unit accepts at the RX input a bi-phase-level,

embedded-clock signal. In this encoding mode, a logic one is

represented by a high-to-low transition within the bit cell, while a logic

zero is represented by a low-to-high transition. The recovered clock

and data signals are presented on CLK and DATB, respectively, with

the data signal inverted. The operating baud rate (in MBaud) is specified by the dash number. The input

baud rate may vary by as much as ±15% from the nominal device baud rate without compromising the

integrity of the information received.

Because the 3D7522 is not PLL-based, it does not require a long preamble in order to lock onto the

received signal. Rather, the device requires at most one bit cell before the data presented at the output is

valid. This is extremely useful in cases where the information arrives in bursts and the input is otherwise

turned off.

The all-CMOS 3D7522 integrated circuit has been designed as a reliable, economic alternative to hybrid

TTL Manchester Decoders. It is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads. It is

offered in space saving surface mount 8-pin and 14-pin SOICs.
