SY89323L中文资料Translators数据手册Microchip规格书

描述 Description

The SY89323L is a dual differential LVPECL-to-LVTTL translator. Because LVPECL (Low Voltage Positive ECL) levels are used, only +3.3V and ground are required. The SY89323L is functionally equivalent to the SY100EPT23L, but in an ultra-small 8-pin MLF® package that features a 70% smaller footprint. The ultra-small package and the dual gate design of the SY89823L make it ideal for applications that require the translation of a clock and data signal in a minimal space. The inputs are compatible with 10k and 100k input levels and any standard differential LVPECL input referenced to a VCC of 3.3V.

• Available in ultra-small 8-pin MLF® (2mm x 2mm) package

简介

SY89323L属于集成电路（IC）的转换器电平移位器。由制造生产的SY89323L转换器，电平移位器逻辑转换器或电平移位器 IC 可用于在数字逻辑设备之间传递信息，这些设备可在不同/不兼容的供电电压下工作，或可实现不同的信令方式。例如，可以将需要 5 V 电源的数字输出传感器连接到具有 3.3 V I/O 电源的 FPGA，或者在 CMOS 或 TTL 等单端信令方式与 PECL 或 LVDS 等差分技术之间进行转换。
