Optional Reference Frequency (REFCLKP/N) Specifications

The CDR operates without any reference clock. However, a reference clock input is available should the user want

to maintain the CDR frequency lock without any data input.

s When using the TRCV012G5 device, a 155.52 MHz differential LVPECL clock can be applied to the

REFCLKP/N input.

s When using the TRCV012G7 device at the OC-48/STM-16 rate, a 155.52 MHz differential LVPECL clock can be

applied to the REFCLKP/N input.

s When using the TRCV012G7 device at the RS FEC OC-48/STM-16 rate, a 166.62 MHz differential LVPECL

clock can be applied to the REFCLKP/N input.

Table 10 provides the characteristics of the REFCLKP/N input.

* Includes effects of power supply variation, temperature, electrical loading, and aging. The ±20 ppm tolerance is

required to meet SONET/SDH requirements if the reference frequency is used for system clocking when timing

recovery is lost.

† Specified range is to be compatible with environmental specification of TRCV012G5 or TRCV012G7. Applications

requiring a reduced temperature range may specify the reference frequency oscillator accordingly.
