2.4 T3 / E3 TRANSMIT FORMATTER SIGNAL DESCRIPTION
Signal Name:
FTSOF
Signal Description:
T3/E3 Transmit Formatter Start Of Frame Sync Signal
Signal Type:
Output / Input
This signal can be configured via the FTSOFC control bit in Master Control Register 1 to be either an
output or an input. When this signal is an output, it pulses for one FTCLK period to indicate a T3 or E3
frame boundary. See Figure 2.4A for an example. When this signal is an input, it is sampled to set the
transmit T3 or E3 frame boundary. See Figure 2.4A for an example. This signal can be configured via
the FTSOFI control bit in Master Control Register 3 (see Section 4.2) to be either active high (normal
mode) or active low (inverted mode).
Signal Name:
FTCLK
Signal Description:
T3/E3 Transmit Formatter Clock
Signal Type:
Input
An accurate T3 (44.736 MHz +/- 20 ppm) or E3 (34.368 MHz +/- 20 ppm) clock should be applied at this
signal. This signal is used to clock data into the transmit T3/E3 formatter. Transmit data can be clocked
into the device either on a rising edge (normal mode) or a falling edge (inverted mode). This option is
controlled via the FTCLKI control bit in Master Control Register 3 (see Section 4.2).
Signal Name:
FTD
Signal Description:
T3/E3 Transmit Formatter Serial Data
Signal Type:
Input
This signal inputs data into the transmit T3/E3 formatter. This signal can be sampled either on the rising
edge of FTCLK (normal mode) or the falling edge of FTCLK (inverted mode). This option is controlled
via the FTCLKI control bit in Master Control Register 3 (see Section 4.2). Also, the data input to this
signal can be internally inverted if enabled via the FTDI control bit in Master Control Register 3 (see
Section 4.2). When T3 C-Bit Parity Mode is disabled, C Bits are sampled at this input. This signal is
ignored when the M13/E13 multiplexer is enabled (see the UNCHEN control bit in Master Control
Register 1). If not used, this signal should be tied low.
Signal Name:
FTDEN
Signal Description:
T3/E3 Transmit Formatter Serial Data Enable or Gapped Clock Output
Signal Type:
Output
Via the DENMS control bit in Master Control Register 1, this signal can be configured to either output a
data enable or a gapped clock. In the data enable mode, this signal will go active when payload data
should be made available at the FTD input. In the gapped clock mode, this signal will act as a demand
clock for the FTD input and it will transition for each bit of payload data needed at the FTD input and it
will be suppressed when the transmit formatter inserts overhead data and hence no data is needed at the
FTD input. In the T3 Mode, overhead data is defined as the M Bits, F Bits, C Bits, X Bits, and P Bits. In
the E3 Mode, overhead data is defined as the FAS word, RAI Bit and Sn Bit (i.e. bits 1 to 12). See Figure
2.4A for an example. This signal can be internally inverted if enabled via the FTDENI control bit in
Master Control Register 3 (see Section 4.2). This signal operates in the same manner even when the
device is configured in the Transmit Pass Through mode (see the TPT control bit in the T3/E3 Control
Register).
