FEATURES
DESCRIPTION
Micrel'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'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.
