Notes:
1) This filter configuration assures a passband ripple compliant with Bellcore GR-1244-CORE to satisfy wander
transfer requirements (<0.2 dB ripple is required) of a network node. It can be used following a system synchronizer
such as the MT9045 to provide clock jitter attenuation while maintaining Stratum 3 compliance. A 155.52 MHz TCLK
output generated with the VCXO PLL configuration will be OC-3 and OC-12 timing jitter compliant.
2) This is a reduced cost and size variant of the above filter, due to the decreased size of C
GR-1244-CORE compliance is not needed.
3) This configuration is used to generate a DS3 clock of 44.736 MHz at the TCLK output. This configuration is
GR-1244-CORE compliant when used following a system synchronizer.
