ADI AD9500BP

Генератор тактовых импульсовНетECL, TTLECL

Overview

The AD9500BP is a digitally programmable delay generator, which provides programmed delays, selected through an 8-bit digital code, in resolutions as small as 10 ps. The AD9500BP is constructed in a high performance bipolar process, designed to provide high speed operation for both digital and analog circuits. The AD9500BP employs differential TRIGGER and RESET inputs which are designed primarily for ECL signal levels but function with analog and TTL input levels. An onboard ECL reference midpoint allows both of the inputs to be driven by either single ended or differential ECL circuits. The AD9500BP output is a complementary ECL stage, which also provides a QR parallel output circuit to facilitate reset timing implementations. The digital control data is passed to the AD9500BP through a transparent latch controlled by the LATCH ENABLE signal. In the transparent mode, the internal DAC of the AD9500BP will attempt to follow changes at the inputs. The LATCH ENABLE is otherwise used to strobe the digital data into the AD9500BP latches.
