MAX3690
+3.3V, 622Mbps SDH/SONET 8:1 Serializer with Clock Synthesis and TTL Inputs
Low-Power 622Mbps Mux
Part Details
- Selectable Reference Clock Frequency: 77.76MHz, 51.84MHz, or 38.88MHz
- Single +3.3V Supply
- 77Mbps (8-bit) Parallel to 622Mbps Serial Conversion
- Clock Synthesis for 622Mbps Serial Data
- 200mW Power
- TTL Parallel Clock and Data Inputs
- Differential 3.3V PECL Serial-Data Output
The MAX3690 serializer is ideal for converting 8-bit-wide, 77Mbps parallel data to 622Mbps serial data in ATM and SDH/SONET applications. Operating from a single +3.3V supply, this device accepts TTL clock and data inputs, and delivers a 3.3V differential PECL serial-data output. A fully integrated PLL synthesizes an internal 622MHz serial clock from a low-speed crystal reference clock (77.76MHz, 51.84MHz, or 38.88MHz).
The MAX3690 is available in the extended-industrial temperature range (-40°C to +85°C) in a 32-pin TQFP package.
Applications
- 622Mbps ATM/SONET Access Nodes
- 622Mbps SDH/SONET Transmission Systems
- Add/Drop Multiplexers
