SL23EP09
Low Jitter and Skew 10 to 220 MHz Zero Delay Buffer (ZDB)
Key Features

10 to 220 MHz operating frequency range
Low output clock skew: 45ps-typ
Low output clock jitter:
The SL23EP09 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.
25 ps-typ cycle-to-cycle jitter
15 ps-typ period jitter
The product has an on-chip PLL which locks to the input
clock at CLKIN and receives its feedback internally from the
CLKOUT pin.

Low part-to-part output skew: 90 ps-typ
Wide 2.5 V to 3.3 V power supply range
Low power dissipation:
The SL23EP09 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).
26 mA-max at 66 MHz and VDD=3.3 V
24 mA-max at 66 MHz and VDD=2.5V
