TUPP™ 2488 ASSP Telecom Standard Product Data Sheet
Function
When not in Payload Processor Loopback Only
mode ETPL_HTPOH[4:1] is an input (HTPOH[4:1])
and is sampled on the rising edge of HPOHCLK.
ETPL_HTPOH[4:1] pins are implemented with
programmable drive I/O. They are controlled by
VDDOPROG_E.
Egress Tributary Payload Frame Pulse and
High Order Transmit Path Overhead Insert
Ready EV5_HTPOHRDY[4:1].
Note: When the device is configured in Payload
Processor Loopback Only mode, High Order
Transmit Path overhead insertion is not supported
and low order egress telecom bus signals are
supported. In this mode the pin functions as
EV5[4:1] output bus.
Note: When the device is not configured in
Payload Processor Loopback Only mode the low
order egress telecom bus signals are not supported
and High Order Transmit Path overhead insertion
is supported. In this mode the pin functions as
HTPOHRDY[4:1] output bus.
Egress Tributary Payload Frame Pulse. The
egress tributary payload frame pulse bus, EV5[4:1],
identifies the tributary synchronous payload
envelope / low order virtual container frame
boundaries on the corresponding egress data bus
(EDATA[4:1][7:0]). EV5[N] is set high to mark the
various V5 bytes on the EDATA[N][7:0] bus.
In Payload Processor Loopback Only mode
EV5_HTPOHRDY [4:1] is an output (EV5) and is
updated on the rising edge of REFCLK.
High Order Transmit Path Overhead Insert
Ready. HTPOHRDY[4:1] is set high during the
most significant bit of a POH byte to indicate
readiness to accept the byte on the
ETPL_HTPOH[4:1] input. This byte will be
accepted if EIDLE_HTPOHEN[4:1] is also set high.
When not in Payload Processor Loopback Only
mode EV5_HTPOHRDY[4:1] is an output
(HTPOHRDY[4:1]) and is updated on the falling
edge of HPOHCLK.TUPP 2488.
EV5_HTPOHRDY[4:1] pins are implemented with
programmable drive I/O. They are controlled by
VDDOPROG_E.
