A Drop Bus Clock: This clock operates at 19.44 MHz for
STM-1/STS-3 operation. A Drop bus byte-wide data (AD7-AD0), the
parity bit (ADPAR), SPE indication (ADSPE), and the C1J1V1 indica-
tion (ADC1J1V1) are clocked in on falling edges of this clock. This
clock may also be used for add bus timing and deriving the
like-named add bus byte-wide data, add and TU/VT indications, and
parity bits.
A Drop Bus Parity Bit: A parity bit input signal representing the odd
or even parity calculation for each data byte, SPE, and C1J1V1 sig-
nal from the drop bus, or the data byte only.
A Drop Bus Data Byte: Byte-wide data that corresponds to the
STM-1/STS-3 signal on the drop bus. The first bit received (dropped)
corresponds to bit 7 which is lead E1.
VDD1: +1.8 volt supply voltage, 5%.
VDD2: +3.3 volt supply voltage, 5%. This supply voltage
should be powered up prior to the 1.8 V (VDD1) supply voltage
or at the same time. This supply voltage must not go below
VDD1 by more than 0.5 V at any time including power down.
Ground: 0 volt reference.
No Connect: NC leads are not to be connected, not even to
another NC lead, but must be left floating. Connection of these
leads may impair performance or cause damage to the device.
