Diodes Incorporated · Clock Generators, PLLs, Frequency Synthesizers · TSSOP-16

PI6C557-03BLE from Diodes Incorporated, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S0 input Select pin 0 for clock output frequency selection with internal pull-up resistor.
2 S1 input Select pin 1 for clock output frequency selection with internal pull-up resistor.
3 SS0 input Spread select pin 0 for spread spectrum selection with internal pull-up resistor.
4 X1/CLK input Crystal or clock input for 25 MHz fundamental mode crystal or single-ended clock.
5 X2 output Crystal connection for external crystal; leave unconnected for clock input mode.
6 OE input Output enable control with internal pull-up resistor; CLK outputs tri-stated when low.
7 GNDX power_in Crystal ground pin.
8 SS1 input Spread select pin 1 for spread spectrum selection with internal pull-up resistor.
9 IREF output Precision current reference output for external series resistor connection; typical 2.32 mA with 475 Ω resistor to ground.
10 CLK1 tri_state HCSL complement clock output (negative differential pair).
11 CLK1 tri_state HCSL clock output (positive differential pair).
12 VDDA power_in Analog supply voltage connect to +3.3 V ±10%.
13 GNDA power_in Output and analog circuit ground pin.
14 CLK0 tri_state HCSL complement clock output (negative differential pair).
15 CLK0 tri_state HCSL clock output (positive differential pair).
16 VDDX power_in Crystal oscillator supply voltage connect to +3.3 V ±10%.
