Product Description

SIT1057QTK/3 uses the S control input to select normal communication or silent operation. In silent mode the transmitter is disabled while the receiver remains available, allowing the controller to observe bus traffic without driving the CAN lines. This mode serves a different purpose from a standby transceiver that waits for a wake-up request.

The /3 option exposes VIO for a 3.3 V or 5 V MCU, and the QTK order uses an eight-terminal DFN with a 3 by 3 mm body. Its 5 Mbps CAN FD data-phase capability applies with a 4.75 to 5.25 V bus supply; the package drawing specifies a 0.65 mm terminal pitch and a 0.8 mm maximum height.
