IDT85304-01

• Five differential 3.3V LVPECL outputs
• Selectable differential CLK, xCLK, or LVPECL clock inputs
• CLK, xCLK pair can accept the following differential input levels:
   LVDS, LVPECL, LVHSTL, SSTL, and HCSL
• PCLK, xPCLK supports the following input types: LVPECL, CML, and SSTL
• Maximum output frequency: 650MHz
• Translates any single-ended input signal to 3.3V LVPECL levels with resistor bias on xCLK input
• Output skew: 35ps (max.)
• Part-to-part skew: as low as 150ps
• Propagation delay: 2.1ns (max.)
• 3.3V operating supply
• Available in TSSOP package

NOTE:
1. Stresses beyond those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolutemaximum- rated conditions for extended periods may affect device reliability.

3.3V LVPECL clock generator-divider. It has two selectable clock inputs. The CLK/ xCLK pair can accept most standard differential input levels. The PCLK/ xPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.

Guaranteed output of IDT85304-01 and part-to-part skew characteristics make the IDT85304- 01 ideal for those applications that demand well-defined performance and repeatability.
