Description
The SL23EP08 is a low skew, low jitter and low power Zero
Delay Buffer (ZDB) designed to produce up to nine (9) clock
outputs from one (1) reference input clock, for high speed
clock distribution applications.
The product has an on-chip PLL and a feedback pin (FBK)
which can be used to obtain feedback from any one of the
output clocks. The SL23EP08 has two (2) clock driver banks
each with four (4) clock outputs. These outputs are controlled
by two (2) select input pins S1 and S2. When only four (4)
outputs are needed, four (4) bank-B output clock buffers can
be tri-stated to reduce power dissipation and jitter. The select
inputs can also be used to tri-state both banks A and B or
drive them directly from the input bypassing the PLL and
making the product behave like a Non-Zero Delay Buffer
(NZDB). The product also offers various 1X, 2X and 4X
frequency options at the output clocks. Refer to the “Product
Configuration Table” for the details.
The high-drive version operates up to 220MHz and 200MHz at
3.3V and 2.5V power supplies respectively.
Benefits
Up to eight (8) distribution of input clock
Standard and High-Dirive levels to control impedance
level, frequency range and EMI
