S2092 AMCC (Applied Micro Circuits Corp), S2092 Datasheet - Page 2

• Manufacturer Part Number: S2092
• Description: Bicmos Pecl Clock Generator Serial Backplane Retimer Device
• Manufacturer: AMCC (Applied Micro Circuits Corp)

S2092 OVERVIEW
The S2092 supports clock recovery from 2.488 Gbps
to 2.67 Gbps data rate. Differential serial data is input
to the chip at the specified rate, and clock recovery is
performed on the incoming data stream. An external
oscillator is required to minimize the PLL lock time.
Retimed data is output from the S2092.
