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.

Page 2 of 18 SL23EP08 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. Rev 1.4, May 28, 2007 Page 3 of 18 SL23EP08 Figure 1.

Output phase is random (0° or 180° with respect to input clock). Use SL23EP08-2 if phase integrity is required.

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.
