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.

General Description
PLL Bypass Mode
The SL23EP08 is a low skew, low jitter Zero Delay
Buffer with very low operating current.
If the S2=1 and S2=0 pins, the on-chip PLL is shutdown
and bypassed, and all the eight (8) output clocks of bank
A and bank B are driven directly from the reference input
clock. In this operation mode SL23EP08 works like a
non-ZDB product.
The product includes an on-chip high performance PLL
that locks into the input reference clock and produces
eight (8) output clock drivers tracking the input
reference clock for systems requiring clock distribution.
in addition to FBK pin used for internal PLL feedback,
there are two (2) banks with four (4) outputs in each
bank, bringing the number of total available output
clocks to eight (8).
Input and output Frequency Range
The input and output frequency range is the same for
SL23EP08-1 and -1H versions. For SL23EP08-2, -2H 3, -4 and -5H versions, the output frequency is 1/2x,
1x, 2x, or 4x of the CLKIN as given in the “Available
SL23EP08 Configurations” Table 3. But, the frequency
range depends on VDD and drive levels as given in the
“Electrical Specifications” Tables.
If the input clock frequency is DC (from GND to VDD),
this is detected by an input frequency detection
circuitry and all eight (8) clock outputs are forced to HiZ. The PLL is shutdown to save power. In this
shutdown state, the product draws less than 10 ȝA
supply current.
High and Low-Drive Product Options
The SL23EP08 is offered with high drive “-1H, -2H and 5H” and standard drive “-1, -2, -3 and -4” options. These
drive options enable the users to control load levels,
frequency range and EMI control. Refer to the AC
electrical tables for the details.
SL23EP08-5H is offered only with high drive option.
SL23EP08-3 and -4 are offered only with standard drive
option.
Skew and Zero Delay
All outputs should drive the similar load to achieve
output-to-output skew and input-to-output delay
specifications given in the AC electrical tables. However,
Zero delay between input and outputs can be adjusted
by changing the loading of FBK pin relative to the banks
A and B clocks since FBK is the feedback to the PLL.
Power Supply Range (VDD)
SpreadThru™ Feature
If a Spread Spectrum Clock (SSC) were to be used as
an input clock, the SL23EP08 is designed to pass the
modulated Spread Spectrum Clock (SSC) signal from
its reference input to the output clocks. The same
spread characteristics at the input are passed through
the PLL and drivers without any degradation in spread
percent (%), spread profile and modulation frequency.
The SL23EP08 is designed to operate with from 3.3V to
2.5V VDD power supply range. An internal on-chip
voltage regulator is used to provide PLL constant power
supply of 1.8V, leading to a consistent and stable PLL
electrical performance in terms of skew, jitter and power
dissipation. The SL2308 I/O is powered by using VDD.
Contact SLI for 1.8V power supply version ZDB called
SL23EPL08.
Select Input Control
The SL23EP08 provides two (2) input select control
pins called S1 and S2. This feature enables users to
selects various states of output clock banks-A and
bank-B, output source and PLL shutdown features as
shown in the Table 2.
The S1 (Pin-9) and S2 (Pin-8) inputs include 250 kȍ
weak pull-down resistors to GND.

Notes:
1. Outputs are inverted on SL23EP08-2, -2H and -3 in PLL bypass mode when S2=1 and S1=0. Use SL23EP08-1 if
non-inverting outputs are required.
2. Output phase is random (0° or 180° with respect to input clock). Use SL23EP08-2 if phase integrity is required.

External Components & Design Considerations
Typical Application Schematic
Comments and Recommendations
Decoupling Capacitor: A decoupling capacitor of 0.1ȝF must be used between VDD and VSS pins. Place the
capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and
to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD
pin.
Series Termination Resistor: A series termination resistor is recommended if the distance between the output
clocks and the load is over 1 ½ inch. The nominal impedance of the clock outputs is given on the page 5. Place the
series termination resistors as close to the clock outputs as possible.
Zero Delay and Skew Control: All outputs and CLKIN pins should be loaded with the same load to achieve “Zero
Delay” between the CLKIN and the outputs. The CLKOUT pin is connected to CLKIN internally on-chip for feedback
to PLL. For applications requiring zero input/output delay, the load at the all output pins including the CLKOUT pin
must be the same. If any delay adjustment is required, the capacitance at the CLKOUT pin could be increased or
decreased to increase or decrease the delay between Bank A and B clocks and CLKIN. For minimum pin-to-pin
skew, the external load at all the Bank A and B clocks must be the same.
