The MT9040 generates ST-BUS clock and framing signals that are phase locked to either a 19.44 MHz, 2.048MHz, 1.544MHz, or 8kHz input reference. The MT9040 is compliant with AT&T TR62411 and Bellcore GR-1244-CORE, Stratum 4; and ETSI ETS 300 011. It will meet the jitter/wander tolerance, jitter transfer, intrinsic jitter, frequency accuracy and capture range for these specifications.
