557G-03LFT from RENESAS, in a TSSOP-16-175mil. 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 | S0 | input | Select pin 0 sets the output frequency together with S1 per Table 1 (25M, 100M, 125M or 200M) and has an internal pull-up resistor. |
| 2 | S1 | input | Select pin 1 sets the output frequency together with S0 per Table 1 and has an internal pull-up resistor. |
| 3 | SS0 | input | Spread select pin 0 sets the spread type and amount together with SS1 per Table 2 and has an internal pull-up resistor. |
| 4 | X1/ICLK | input | Crystal or clock input, to be connected to a 25 MHz crystal or a single-ended clock. |
| 5 | X2 | output | Crystal connection, to be left unconnected when a clock is applied to X1/ICLK. |
| 6 | OE | input | Output enable; a low level tri-states the outputs without shutting the device down, and it has an internal pull-up resistor. |
| 7 | GNDXD | power_in | Connect to ground. |
| 8 | SS1 | input | Spread select pin 1 sets the spread type and amount together with SS0 per Table 2 and has an internal pull-up resistor. |
| 9 | IREF | output | Precision reference resistor pin connected to the internal current reference; RR = 475 Ω (1%) gives IREF of 2.32 mA for a 50 Ω board trace. |
| 10 | CLK1 | output | HCSL complementary clock output 1. |
| 11 | CLK1 | output | HCSL true clock output 1. |
| 12 | VDDODA | power_in | Connect to a +3.3 V supply for the output driver and analog circuits. |
| 13 | GNDODA | power_in | Connect to ground. |
| 14 | CLK0 | output | HCSL complementary clock output 0. |
| 15 | CLK0 | output | HCSL true clock output 0. |
| 16 | VDDXD | power_in | Connect to a +3.3 V supply for the crystal oscillator and digital circuits. |
