Description
The SL23EP08 is a low skew, low jitter and low power
Zero Delay Buffer (ZDB) designed to produce up to eight
(8) 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, 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 SL23EP08 offers
various X/2,1X, 2X and 4X frequency options at the output
clocks. Refer to the “Product Configuration Table” for the
details.
The SL23EP08-1H, -2H and 5H versions operates up to
220 MHz and SL23EP08-1, -2, -3 and -4 versions operate
up to 133 MHz with CL=15pF output load.
Benefits
Up to eight (8) distribution of input clock
Standard and High-Dirive levels to control
impedance level, frequency range and EMI
Low skew, jitter and power dissipation
