Description
The SL2309 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 which locks to the input
clock at CLKIN and receives its feedback internally from
the CLKOUT pin.
The SL2309 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 high-drive (-1H) version operates up to 140MHz and
low drive (-1) version operates up to 100MHz at 3.3V.
Benefits
Up to nine (9) distribution of input clock
Standard and High-Dirive levels to control impedance
level, frequency range and EMI
Low power dissipation, jitter and skew
Low cost
