Transceiver I/O Truth Table
X = Don't Care
Notes:
1. In-Band EI ≤ 115.2 kb/s and FIR_SEL = 0.
2. In-Band EI ≥ 0.576 Mb/s and FIR_SEL = 1.
3. Logic Low is a pulsed response. The condition is maintained for duration dependent on the pattern and strength of the incident intensity.
4. To maintain low shutdown current, TXD needs to be driven high or low and not left floating.
Notes:
5. CX1 must be placed within 0.7 cm of the HSDL-3602 to obtain optimum noise immunity.
6. In "HSDL-3602 Functional Block Diagram" on page 1 it is assumed that Vled and V
