HSS_TXCLK and HSS_RXCLK may be coming from external independent sources or being driven by the
IXP42X product line and IXC1100 control plane processors. The signals are shown to be synchronous
for illustrative purposes and are not required to be synchronous.
Applicable when the HSS_RXFRAME and HSS_TXFRAME signals are being driven by an external source
as inputs into the IXP42X product line and IXC1100 control plane processors. Always applicable to
HSS_RXDATA.
The HSS_RXFRAME and HSS_TXFRAME can be configured to accept data on the rising or falling edge of
the given reference clock. HSS_RXFRAME and HSS_RXDATA signals are synchronous to HSS_RXCLK
and HSS_TXFRAME and HSS_TXDATA signals are synchronous to the HSS_TXCLK.
Applicable when the HSS_RXFRAME and HSS_TXFRAME signals are being driven by the IXP42X
product line and IXC1100 control plane processors to an external source. Always applicable to
HSS_TXDATA.
The HSS_TXCLK can be configured to be driven by an external source or be driven by the IXP42X
product line and IXC1100 control plane processors. The slowest clock speed that can be accepted or
driven is 512 KHz. The maximum clock speed that can be accepted or driven is 8.192 MHz. The clock
duty cycle accepted will be 50/50 + 20%.
Timing tests were performed with a 70-pF capacitor to ground and a 10-KΩ pull-up resistor.
