1-to-1 2.5V, 3.3V 830S21I Differential-to-LVCMOS/LVTTL Translator Datasheet General Description Features 830s21I is a 1-to-1 Differential-to- LVCMOS/ LVTTL translator and One LVCMOS/LVTTL output a member of the family of High Performance Clock Solutions from Differential CLK, nCLK input pair IDT. The differential input is highly flexible and can accept the CLK, nCLK pair can accept the following differential following input types: LVPECL, LVDS, LVHSTL, SSTL and HCSL. input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL The small 8-lead SOIC footprint makes this device ideal for use in Maximum output frequency: 350MHz applications with limited board space. Part-to-part skew: 525ps (maximum) Additive Phase jitter, RMS: 0.11ps (typical) Small 8 lead SOIC package saves board space Full 3.3V and 2.5V operating supply -40C to 85C ambient operating temperature Available in lead-free (RoHS 6) package Block Diagram Pin Assignment nc 1 8 VDD Pullup/Pulldown CLK CLK Q 2 7 Q nCLK nc 3 6 Pullup/Pulldown nCLK VBB 4 5 GND VBB 830s21I 8-Lead SOIC 3.9mm x 4.9mm x 1.375mm package body M Package Top View 2015 Integrated Device Technology, Inc 1 December 10, 2015830S21I Datasheet Table 1.
