Transmit Parallel Clock Output TTL. TPCO_i (i = 0, 1, 2, 3) is a flow-
through or divided version of TPCI_i or RPCI_i. XmtCOCnf (register
T_COCNF) configures the TPCO_i (i = 0, 1, 2, 3) outputs as a 77.76
MHz/38.88 MHz/19.44 MHz/8-KHz clock.
When Intel IXF6048 is configured as a single STS-12/STM-4/STS-3
(non-concatenated or concatenated) transceiver, TPCO_1, TPCO_2,
and TPCO_3 are tristated
XmtTimRef (register T_COCNF) configures the transmitter in two
different modes:
NOTE: In the line loopback mode of operation, the TPCO_i clocks are
Transmit Frame Position Input TTL. TFPI is the active-high frame
position input. TFPI can only be used when the four transmit channels
use the common clock input (TPCI_0). TFPI is used to align the SONET/
SDH frames generated by the four transmit channels to an external 8-
KHz system reference.
The byte position indicated by TFPI is selected by configuring
XmtFPICnf[7:0] (global register T_FPCNF). TFPI should be active-high
for a single TPCI_0 period.
TFPI is sampled on the rising edge of TPCI_0.
If it is not required that the frames are aligned to an external source,
TFPI have to be tied to GND
Transmit Frame Position Output TTL. TFPO is an active-high frame
position output. TFPO is an active-high pulse indicating the position of
the SONET/SDH frame on the TPDO_0[7:0].
The byte position indicated by TFPO is selected by configuring
XmtFPOCnf[7:0] (global register T_FPCNF). TFPO is active-high for a
single TPCI_0 period.
TFPO is updated on the rising edge of TPCI_0.

• Clocked by the receive parallel clock input RPCI_i (XmtTimRef =
'10')
'01')
derived from the RPCI_i clock input, because the transmitter's
internal clock source is automatically switched to the RPCI_i
clock input in that case.
