DESCRIPTION
The SY100E222L is a low-skew, low-jitter device capable of receiving a high-speed LVECL/LVPECL input in either a single-ended or differential configuration. For single-ended configurations, a VBB output reference is supplied by the SY100E222L. A 2:1 input multiplexer selects from two differential input pairs by means of the CLK_SEL input select. The internal programmable divider for each of the four banks generates a /1 or /2 frequency of the selected input. The /1//2 divider outputs can be asynchronously synchronized with the master reset (MR) input so that the outputs will start out in a known state. The 15 total outputs are partitioned into four independently selected output banks in a 2/3/4/6 fanout configuration. Each of the four banks can independently select the /1 or /2 output frequency by means of the four separate frequency select pins (FSELA-FSELD) inputs. The SY100E222L is pin-for-pin compatible with the MC100LVE222FA device. The SY100E222L is part of a Micrel's Precision Edge(R) product family. For other integrated clock divider plus fanout buffer options, consider Micrel's SY89200 family. All support documentation can be found on Micrel's web site at: www.micrel.com.

Notes: 1. Permanent device damage may occur if the ratings in "Absolute Maximum Ratings" section are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Due to the limited drive capability use for input of the same package only. 4. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. 5. Input and output parameters are for VCC = 3.3V. They vary 1:1 with VCC. 6. VIHCMR is defined as the range within which the VIH level may vary with the device still meeting the propagation delay specification. The VIL level must be such that the peak-to-peak voltage is less than 1.0V and then greater than or equal to VPP(min).

5. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. 6. VIHCMR is defined as the range within which the VIH level may vary with the device still meeting the propagation delay specification. The VIL level must be such that the peak-to-peak voltage is less than 1.0V and then greater than or equal to VPP(min). 7. High-frequency AC parameters are guaranteed by design and characterization. 8. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the differential output signals. 9. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal. 10. The within-device skew is defined as the worst-case difference between any two similar delay paths within a single device. 11. VPP(min) is defined as the minimum input differential voltage, which will cause no increase in the propagation delay. The VPP(min) is AC limited for the SY100E222L as a differential input as low as 50 mV will still produce full ECL levels at the output.
