SY733021U 2.5/3.3V 1-to-1 Differential to LVCMOS/LVTTL Translator Precision Edge(R) General Description Features Micrel's SY733021U is a 1-to-1, differential-to-LVCMOS / LVTTL translator. The differential input is highly flexible and can accept LVPECL, LVDS, LVHSTL, SSTL, and HCSL input types. SY733021U is part of Micrel's Precision Edge product line, is pin-to-pin compatible with IDT's ICS83021I and is available as a Pb-free 8-pin SOIC in either tube or tape and reel packaging. The SY733021U runs on a 2.5V (5%) or a 3.3V (10%) power supply and is guaranteed over the full industrial temperature range (-40C to +85C). * Differential LVPECL, LVDS, LVHSTL, SSTL, and HCSL inputs * 350MHz maximum frequency * Additive phase jitter: - 90fsRMS, 100MHz (637kHz to 10MHz) * <500ps part-to-part skew * 1.9ns typical propagation delay (VCC = 2.5V) * 2.5V 5% or 3.3V 10% power supply operation * -40C to +85C industrial operating temperature * Available in 8-pin SOIC lead-free package Datasheets and support documentation are available on Micrel's web site at: www.micrel.com.

Permanent device damage may occur if absolute maximum ratings 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 may affect device reliability. 4. The datasheet limits are not guaranteed if the device is operated beyond the recommended operating conditions. 5. The circuit is designed to meet the DC specifications shown in the above tables after thermal equilibrium has been established. 6. Outputs terminated with 50 to VCC/2. See Parameter Measurement Set-Up. 7. VIHCMR maximum varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the differential input signal.
