1 Contents 1 Introduction Interposer board selection and configurations s Additional Interposer Board (IB) Features Appendix A: Bill of Materials (BOM) Revision control Introduction The SiT6911EB series of interposer boards (IB) are designed for use with SiTime s Elite Platform Super-TCXOs. These IBs enable system level testing of the in an existing TCXO or OCXO footprint on the target board without PCB changes. The IBs are available in 14 distinct designs to accommodate a total of 38 TCXO and OCXO footprints. Additional designs may be added per user demand. Refer to section 2 for details on IB selection vs desired footprint. Below is an example of an IB that is compatible with four quartz TCXOs: RPT7050A, RPT7050P, Epson TG-5501CA, and Taitien TT type. Pogo pins and soldering points on the target board Figure 1. 3D View of SiT6911EB_rev2_I7VE4_6 Interposer Each IB design can accommodate a number of TCXO and/or OCXO footprints. SiTime typically ships the IB with the pogo pin positions preconfigured for a specific footprint per customer request. The user can then solder the pogo pins to the PCB directly for system level testing. The IB can also be reconfigured by the user for a different footprint for which the IB is designed. Refer to Table 1, Table 2, and Table 3 for details of the board configuration vs. different footprints. IBs are intended for electrical and functional evaluation only. They provide excellent signal integrity when properly soldered. They should not be used for environment testing such as vibration or for qualification purposes. SiT6911EB Manual Rev Page 1 of 22

2 2 Interposer Board Selection and Configurations Each SiT6911EB_rev2_XXXXX interposer board (IB) can be configured via pogo pin positions and resistors (R1, R2, R3, R4, R5, and R6) for different TCXO/OCXO package sizes and footprints. Table 1, Table 2, and Table 3 summarize the mapping of 18 TCXO part numbers, 7 OCXO part numbers and 38 footprints to the corresponding SiT6911EB_rev2_XXXXX designs, ordering part numbers and resistors configurations. Note that in the tables below 1. x means the resistor in question does not exist 2. - means that the resistor in question should NOT be placed Table 1: Interposer Boards (IBs) for TCXO Footprints Quartz TCXO RPT7050A # of pins Size mm x mm 6 7.0x5.0 VC/OE Options Resistor(s) R1 R2 R3 R4 R5 R6 VC - 0 Ω X X X X IB Design ID IB Ordering Code SiT6911EBV2-I7-6L-V OE 0 Ω - X X X X SiT6911EBV2-I7-6L-O RPT7050P RXO7050M VC - 0 Ω X X X X SiT6911EBV2-I7-6L-V 6 7.0x5.0 SiT6911EB- OE 0 Ω - X X X X I7VE4_6_ SiT6911EBV2-I7-6L-O rev x5.0 OE 0 Ω - X X X X SiT6911EBV2-I7-4L-O EPSONTG- 5501CA Taitien TT Type Kyocera KT7050A EPSON TG- 5500CA 4 7.0x5.0 VC - 0 Ω X X X X SiT6911EBV2-I7-4L-V 4 7.0x 5.0 VC - 0 Ω X X X X SiT6911EBV2-I7-4L-V x x5.0 TXC 7n x5.0 RPT5032A RPT5032P RPT5032A RPT5032P EPSON TG5032CBN/ TG5032SBN Vectron TX-550 Vectron VT-501 VC - 0 Ω - X X X SiT6911EBV2-I7-10L-V OE 0 Ω - 0 Ω X X X SiT6911EBV2-I7-10L-O VC - 0 Ω - X X X SiT6911EB- I7V10 SiT6911EBV2-I7-10L-V OE 0 Ω - 0 Ω X X X rev.2.0 SiT6911EBV2-I7-10L-O OE 0 Ω - 0 Ω X X X SiT6911EBV2-I7-10L-O VC - 0 Ω - X X X SiT6911EBV2-I7-10L-V x3.2 OE - 0 Ω x3.2 OE - 0 Ω X X X X X SiT6911EBV2-I5-10L-O 6 5.0x3.2 OE 0 Ω X X X X X SiT6911EB- SiT6911EBV2-I5-6L-O I5VE4_6_ x3.2 OE 0 Ω X X X X X rev.2.0 SiT6911EBV2-I5-6L-O X X X SiT6911EB- I5V10 SiT6911EBV2-I5-10L-O rev x3.2 OE 0 Ω - X X X X SiT6911EBV2-I5-10L-O x 9.0 VC 0 Ω X X X X X SIT6911EB- SiT6911EBV2-I11-4L-V 11x90E x12.0 VC 0 Ω X X X X X rev.2.0 SiT6911EBV2-I11-4L-V SiT6911EB Manual Rev Page 2 of 22

20 4 Additional Interposer Board (IB) Features Each interposer board contains pins that can be used to connect external signal/equipment and power to the s, or to add decoupling capacitors and configuration resistors for routing VC or OE signals to various target footprint pads. The IB(s) also come with two headers (P1 and P2) to support the I 2 C interface available in all of the Super-TCXO(s). P1 is used to access I 2 C functionality for in-system programming of output frequencies. Pin 2 is used to select one of the two frequencies preprogrammed into the Super-TCXO (available in future Super-TCXO variations). Table 5 lists the P1 and P2 headers supported on the boards. Table 5: List of Connectors Connectors Part number Functional purpose P1 P2 Digi-Key p/n: S1012E-02-ND Digi-Key p/n: S1012E-01-ND Connector P1 is provided for connecting to I 2 C signals: SLA and SDA. Connector P2 is provided for connecting to an optional frequency select signal, FS1 (available in future variations) SiT6911EB Manual Rev Page 20 of 22
