2.1 Board Features
- 2-bit, dual supply level shifter with auto sensing
- VCCA can be between 0.7 V to 1.98 V, and VCCB can be between 0.7 V to 1.98 V
- Signals to be shifted are to be connected to A2/A1 or B2/B1 and the shifted signals are
available on B2/B1 or A2/A1
2.2 Board Description
P3A9606JK can be used as a standalone level shifter when a CERES is not available for evaluation
and testing. The user can manually connect the signals to be shifted to port
A1/A0 and B1/B0 of the P3A9606JK. External VCCA/VCCB can be manually selected and connected to
the evaluation board.
As default, P3A9606JK-EVB evaluation board is configured (with jumper settings) to be mated to a
CERES motherboard serial expansion bus as a level shifter on the SPI bus. If needed,
P3A9606JK-EVB evaluation board can be bypassed using jumper settings to remove it from the SPI
The evaluation boards are shipped with a P3A9606JK soldered on as
U1; a socket (
U2 on the
schematic) can be used in place of
U1 to allow the user the flexibility of repeatedly replacing
P3A9606JK multiple times.
U2 share the same PCB footprint, therefore,
U1 must be removed
U2 as a socket can be installed.
