15
The proper parts are specified for Q2 and Q3 of the reference design; OnSemi BC847BP
DW1T1G and
OnSemi BC847BDW1T1G respectively.
16
The proper transistors are specified for Q4 and Q5 of the reference design; Zetex FCX690B or STM
2STF1360 for Q4 and Zetex FCX790A or STM 2STF2360 for Q5 for the 1Ap-p transmit amplifier
(Zetex ZXT690B and ZXT790A respectively for the 2Ap-p amplifier).
17
If the BIU, PKD, or TXON signals are connected to LEDs, the appropriate current limiting resistor has
been included to limit the current to ≤12mA.
18
If BIU, PKD, or TXON are connected to LEDs and there is a creepage path of ≤1cm from user
accessible points to the signal lines, then ESD protection diodes are included on these signal lines (and
V
DD5
bypass capacitors are also included directly adjacent to the protection diodes).
19
The ICTMode pin is tied to ground for PL 3120 and PL 3170 Smart Transceiver-based devices and
pulled low through a 3kΩ to 5kΩ resistor for PL 3150 Smart Transceiver-based devices (allowing tri-
state control of memory interface lines during in-circuit-test).
20 The CLKSEL pin of the Smart Transceiver is tied high.
21
Any device connected to the RESET~ pin of the Smart Transceiver has an open-drain (or equivalent)
output.
22
If external devices are connected to the RESET~ pin, then a bypass capacitor(s) of 100pF to 1000pF are
included on the RESET~ line within 15mm of the Smart Transceiver pin.
23
For PL 3150 Smart Transceiver-based devices, an LVI that stretches reset events to ≥10ms and has a
threshold range of 4.5V to 4.75V, or tighter, has been specified (e.g., Maxim DS1813-5).
24
If an external oscillator is fed to the XIN pin of the Smart Transceiver (instead of connecting a crystal
between the XIN and XOUT pins) then a power-on-pulse stretching LVI with a delay of ≥10ms is used.
