**Texas Instruments** · Clock Generators, PLLs, Frequency Synthesizers · TSSOP-14

CDCEL913IPWRQ1 from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Xin/CLK | input | Crystal oscillator input or LVCMOS clock input, selectable through the I2C bus. |
| 2 | S0 | input | User-programmable LVCMOS control input S0 with a 500-kΩ internal pullup; S0 is a control pin only and is not multi-use. |
| 3 | VDD | power_in | 1.8-V power supply for the device (recommended 1.7 V to 1.9 V). |
| 4 | Vctr | input | VCXO control voltage input; leave open or pull up when not used. |
| 5 | GND | power_in | Ground. |
| 6 | VDDOUT | power_in | For CDCEL913-Q1, 1.8-V supply for all outputs (recommended 1.7 V to 1.9 V). |
| 7 | VDDOUT | power_in | For CDCEL913-Q1, 1.8-V supply for all outputs (recommended 1.7 V to 1.9 V). |
| 8 | Y3 | output | LVCMOS output; output current limited to ±8 mA at VDDOUT = 1.8 V with 15-pF maximum load. |
| 9 | Y2 | output | LVCMOS output; output current limited to ±8 mA at VDDOUT = 1.8 V with 15-pF maximum load. |
| 10 | GND | power_in | Ground. |
| 11 | Y1 | output | LVCMOS output; output current limited to ±8 mA at VDDOUT = 1.8 V with 15-pF maximum load. |
| 12 | SCL/S2 | input | Serial clock input SCL (default, with 500-kΩ internal pullup) or user-programmable LVCMOS control input S2 (500-kΩ internal pullup) when reconfigured in EEPROM. |
| 13 | SDA/S1 | bidirectional | Bidirectional serial data SDA (default, LVCMOS internal pullup) or user-programmable LVCMOS control input S1 (500-kΩ internal pullup) when reconfigured in EEPROM. |
| 14 | Xout | output | Crystal oscillator output; leave open or pull up when not used. |
