Equal length
3. Differential pair trace layout from VT6307S to 1394
connector must be parallel
1. VT6307S to Connector max length is 7"
2. Differential pair impedance is 110 ohms +- 6 ohms
Layout Note:
Crystal Placement
Crystal must be place as close as
possible to the Chip. Keep traces
all on one PCB layer.
Note:
Close to 1394 CONN.
