I/O Signal Level
Description
No Connect.
These pins are not used by the Si5020C-BA board.
The pins are not connected to circuitry on the
board.
5 VDC
Supply Voltage.
Nominally 5.0 VDC.
GND
Supply Ground.
Nominally 0.0 VDC.
I
*See note. ^{Serial Data Input.}
Equivalent to Si5020 DIN+ and DIN–, respectively.*
I
*See note. ^{Reference Clock Input.}
Equivalent to Si5020 REFCLK+ and REFCLK–,
respectively.*
O
TTL
Lock Detect Output.
Driven high when Si5020 is locked to serial data
input signal. Driven low when out of lock. This sig-
nal is an inverted and level shifted version of the
Si5020 LOL output.*
O
*See note. ^{Serial Data Output.}
Equivalent to Si5020 DOUT– and DOUT+, respec-
tively.*
O
*See note. ^{Serial Clock Output.}
Equivalent to Si5020 CLKOUT– and CLKOUT+,
respectively.*
