Function
Positive Power Supply for the analog receiver
Power Supply: Ground for the analog receiver
Positive Power Supply for the analog
transmitter
Power Supply: Ground for the analog
transmitter
Power Supply: Ground for digital subcircuits
(0 V)
For correct operation, all three pins have to be
connected to ground.
Positive Power Supply
for the digital subcircuits (5.0 V)
For correct operation, all three pins have to be
connected to positive power supply.
Reset
A high signal on this pin forces the FALC
into reset state. During Reset the FALC
needs active clocks on pins SCLKR, SCLKX,
XTAL1 and XTAL3 (E1: XTAL3 only, if slicer
mode selectable by LIM1.JATT/RL = 10 will be
used).
During Reset
- all unidirectional output stages are in high-
impedance state, except pins CLK16M,
CLK12M, CLK8M, CLKX, FSC, XCLK and
RCLK (active clocks are required during reset on
pins SCLKR, SCLKX, XTAL1 and XTAL3
- all bidirectional output stages (data bus) are in
input mode if signal RD is “high”
