Integrated Device Technology Timing Device Nomenclature There are several part number types in the IDT high-performance timing nomenclature. IDT has acquired product lines from both ICS and Freescale and the established part numbers have been maintained. The timing families can be identified by their marketing part number prefix and are defined in the following charts. TIMING NOMENCLATURE 1 Packing Designator T = Shipped in Tape & Reel Blank = Bulk packing (e.g. tube or tray) IDT A V B C D ZZZ R -XXX PP G I T Operating Temperature Range I Blank = 0C to 70C W1 = AEC-Q100 Grade 1 (-40 to +125C) I = -40C to 85C W2 = AEC-Q100 Grade 2 (-40 to +105C) E = -20C to +70C W3 = AEC-Q100 Grade 3 (-40 to +85C) R = -20C to +85C W4 = AEC-Q100 Grade 4 (0 to +70C) G Optional Package Designator G = RoHS 6/6 packaging Blank: RoHS 5/6 packaging PP Package -XXX Optional Dash Number R Revision (optional) ZZZ Specific Part Number Usually one to four digits in length. A dash-number can modify the function. Last two digits may optionally indicate number of outputs D Programmable Clocks or Special Process Technology (optional) E = EPROM S = SiGe EE = EEPROM N = FemtoClock NG R = Masked ROM M = Clock IC with integrated MEMS resonator Output Signaling C 0 = LVCMOS 5 = CML/DCM 1 = HCSL (DIFF) 6 = AMI 2 = HSTL 7 = Analog or Sinusoidal 3 = LVPECL 8 = SSTL 4 = LVDS 9 = Mixed or Programmable Outputs Product Function B 1 = VCXO 3 = Fan Out Buffer 4 = Synthesizer or Frequency Translator (programmable clocks use the optional D character) 5 = SSCG: 1 input, 1 output devices only 6 = Zero-delay Buffer (with and without frequency translation) 7 = Programmable dividers 8 = Application Specific Products Lowest Supported Supply Voltage, or Custom Part Number V V = 3.3 V C = Custom part number T = 2.5 V E = Custom part number P = 1.8 V S = Custom part number U = 1.5 V N = 5x7 parts (new numbering scheme included within) K = 1.2 V S = Clone: Competitor part number follows Product Family A 4 = MEMS Products 6 = Custom Consumer 5 = General Purpose Consumer 8 = Networking, Communication The IDT prefix indicates that the device is part of the timing line of products from IDT. IDT This prefix should not be included as part of the orderable part number.

See datasheet for details. Other non-standard temperature ranges indicated on the datasheet. PP Package R Revision Devices are initially provided at the A revision. Improvements are released using subsequent letters of the alphabet. ZZZ Specific Part Number Usually one to four digits in length. A dash-number suffix can modify the function. Last two digits may optionally indicate number of outputs. Special Process Technology (optional) D D = Clock Data Recovery device S = Device uses SiGe fab process. Absence of S indicates that the part is in another process, usually CMOS or Bipolar. C Output Signalling or Part of the Specific Part Number 0 = LVCMOS 1 = HCSL/DCM (PCI Express) 2 = HSTL 3 = LVPECL 4 = LVDS 5 = CML 8 = SSTL 9 = Selectable Product Function B 1 = VCXO based device 2 = Internal use only 3 = Non PLL Buffer, single-ended outputs 4 = PLL frequency Synthesizer (internal feedback, input is usually a crystal) 5 = Non PLL Buffer, differential outputs 6 = PLL Zero Delay Buffer (no frequency multiplication/division) 7 = a) Non PLL Buffer/Dividers b) PLL based frequency multiplication/division (external feedback, zero delay type PLLs. Usually use a reference clock rather than a crystal input. 8 An 8 in the first digit location indicates that the product is in the Networking/Communications line of timing products for enterprise-class applications. ICS The Integrated Circuit Systems (ICS) prefix indicates that the device is part of the timing line of products from IDT. This is a marketing prefix only, and is not contained in the orderable part number. INTEGRATED DEVICE TECHNOLOGY www.idt.com IDT TIMING DEVICE NOMENCLATURE 2
