PI6C49S1504
High Performance Selectable 1:4 Differential Fanout Buffer
Features
ÎÎ4 differential outputs with 2 banks
ÎÎUser configurable output signaling standard for each bank:
LVDS or LVPECL or HCSL
ÎÎLVCMOS reference output up to 200MHz
ÎÎUp to 1.5GHz output frequency for differential outputs
ÎÎUltra low additive phase jitter: < 0.03 ps (typ) (differential
156.25MHz, 12KHz to 20MHz integration range)
ÎÎSelectable reference inputs support either single-ended
or differential or Xtal
ÎÎLow skew between outputs within banks (<40ps)

ÎÎTSSOP-28 package
Description
The PI6C49S1504 is a high performance fanout buffer device-
which supports up to 1.5GHz frequency. The device also uses
Pericom's proprietary input detection technique to make sure
illegal input conditions will be detected and reflected by output
states. This device is ideal for systems that need to distribute low
jitter clock signals to multiple destinations.
Applications
ÎÎNetworking systems including switches and Routers
ÎÎHigh frequency backplane based computing and telecom
platforms
