Transmitter Outputs
Transmit Serial Data. Serial data stream signals, normally con-
nected to an optical transmitter module. Output return loss, S
-12dB at 15 GHz.
Transmit Serial Clock. Serial clock signals, normally connected to a
lab test equipment or an optical laser module.
Parallel Clock. A 622.08 MHz (or equivalent FEC/10 Gigabit Ether-
net rate) reference clock. It is normally used to coordinate data trans-
fers between upstream logic and the S19252 device.
155.52 MHz Clock Output. 155.52 MHz (or equivalent FEC/10 GbE/
10 G FC rates) clock output from CSU_REFCLK. The output can be
connected to the reference clock input (CRU_REFCLKP/N) of the
clock recovery function.
Transmit Lock Detect. Active high. Goes active after the PLL has
locked to the clock provided on the CSU_REFCLK pins.
TX_LOCKDET is an asynchronous output.
Phase Error. Pulses high during each PCLK cycle for which there is
a potential FIFO overrun/underrun condition. No additional external
components required. Should be directly connected to PHINIT
through serial bus register.
Phase Detector Output. This output is used to drive an external
charge pump which, in turn, drives the external VCO. The external
VCO output is then fed into the CSU_INP/N input to be used as the
transmit reference clock for the CSU block.
Transmit Built-In Self Test Error. This output indicates a bit error in
the transmit built-in self test loop.
