PM5343 STXC
SONET/SDH TRANSPORT OVERHEAD TRANSCEIVER
power supply connections must all be utilized and must all connect to a
common +5 V or ground rail, as appropriate. There is no low impedance
connection within the STXC between the core and pad ring supply rails.
Failure to properly make these connections may result in improper operation
or damage to the device.
2. Inputs RSTB, MBEB and ALE have internal pull-up resistors.
3. Inputs RSICLK, RSIN, TSICLK and SCPI[3:0] have internal pull-down
resistors.
4. All STXC inputs and bidirectionals present minimum capacitive loading and
operate at TTL logic levels except for the TXCI+, TXCI-, RXC+, RXC-, RXD+,
and RXD- differential inputs which operate at pseudo ECL (PECL) logic
levels.
5. Most STXC digital outputs and bidirectionals have 4 mA drive capability,
except the GRICLK and GTICLK outputs which have 8 mA drive capability.
All 4 mA and 8 mA outputs are slew rate limited, except TSOUT. Differential
outputs TXCO+, TXCO-, TXD+, TXD- operate at pseudo ECL (PECL) logic
levels.
6. When receive bit serial mode is enabled (RSER = 1), GRICLK must be
shorted to RICLK. The external capacitance must not exceed 30 pF.
7. When transmit bit serial mode is enabled (TSER = 1), GTICLK must be
shorted to TICLK. The external capacitance must not exceed 30 pF.
