FIFORD
O
FIFO Read Bar
When the device is configured as a Source, this output pulses low during FIFOEN
mode enabling data from a FIFO to be loaded into the input data latch for
transmission.
RDYFORDTA
O
Ready For Data
This signal is high when the input data latch is available for new data to be loaded in.
When the data is loaded, RDYFORDTA goes low until the word is dumped into the
output shift register.
ENV
O
Envelope
This output envelopes the serial output data by being high during transmission.
TXDMXD
O
Transmit Data / Manchester Data
Serial NRZ data out or Manchester Data out depending on the TXSELECT mode.
TXCMXD
O
Transmit Clock / Manchester Data Bar
Output shift clock or Manchester Data Bar depending on the TXSELECT mode.
G20MHZ
O
Gated 20 Mhz
A gated 20 Mhz clock used in conjunction with Transmit Data, Transmit Clock and
Envelope to generate Manchester data using other Aeroflex encoders such as the
CT1698.
TXSELECT
I
Transmit Mode Select. (Internal Pulldown)
"1" = Serial output format is Manchester Data and Data Bar.
"0" = Output will be NRZ Data and Shift Clock.
RXDATA
I
Received Data
Received serial NRZ Data in.
RXCLOCK
I
Received Clock
Received Shift Clock In.
TEST
I
Test Mode Bar (Internal Pullup)
A low on this pin puts the device into an internal wrap-around test mode. Transmit Data
and Transmit Clock are internally connected to Received Data and Received Clock.
The circuit must be in Source mode and only 32 bit data loads and reads are allowed.
In this mode, STR2 loads the full 32 bits for transmission. When this word is wrapped
back, RCVDTA will pulse low indicating reception of a data or command word. STR1
enables the received data latch to be read out. Transmission of control frames can also
be tested in this mode using the regular LDCNTRL and RCVCNTRL signals.
BIT4IN
O
Bit Four In
Fourth bit of received Type E control frame.
BIT4OUT
I
Bit Four Out (Internal Pullup)
Fourth bit of Type E control frame to be transmitted.
SYNCIN
O
Sync In
Sync position of the Received Data Latch.
CFRMSYNC
O
Control Frame Sync In
Sync position of the Received Control Frame Latch
PRTYIN
O
Parity In
Parity bit position of the Received Data Latch.
