SY89537L数据手册集成电路（IC）的时钟发生器PLL频率合成器规格书PDF

描述 Description

The SY89537L integrated programmable clock synthesizer and fanout is part of a precision PLL-based clock generation family optimized for enterprise switch, router, and multiprocessor server applications. This family is ideal for generating internal system timing requirements up to 700MHz for multiple ASICs, FPGAs, and NPUs. These devices integrate the following blocks into a single monolithic IC:

PLL (Phase-Lock-Loop) based synthesizer

Fanout buffers

Clock generator (dividers)

Logic translation (LVPECL, LVDS)



Five independently programmable output banksThis level of integration minimizes additive jitter and part-to-part skew associated with discrete alternatives, resulting in superior system-level timing with reduced board space and power. For applications that require a zero-delay function, see the SY89538L.

特性 Features

• Integrated programmable synthesizer with multiple output dividers, fanout buffers, and clock drivers
