FEATURES
DESCRIPTION
Micrel-Synergy's SY89426 Multi-Output Phase Locked
Loop (PLL) is a SONET compliant clock generator providing
622.08MHz, 155.52MHz and retimed reference clock
outputs. The PLL produces low jitter OC-12/STS-12 and
OC-3/STS-3 rate clocks from an input reference clock of
38.88, 51.84, or 77.76MHz. Additionally, the input reference
clock is retimed and provided as a TTL/CMOS compatible
output, which may be disabled to minimize switching noise.
The SY89426 operates from a single +5 volt supply, and
requires only a simple series RC loop filter.
Coupling Micrel-Synergy's advanced PLL technology
with our proprietary ASSET bipolar process has produced
a clock generator IC which exceeds applicable Bellcore
and ANSI specifications, while setting a new standard for
performance and flexibility.
