MAX3693 19-4775 Rev 2 5/04 +3.3V, 622Mbps, SDH/SONET 4:1 Serializer with Clock Synthesis and LVDS Inputs General Description Features The MAX3693 serializer is ideal for converting 4-bit- Single +3.3V Supply wide, 155Mbps parallel data to 622Mbps serial data in 155Mbps (4-bit-wide) Parallel to ATM and SDH/SONET applications. Operating from a 622Mbps Serial Conversion single +3.3V supply, this device accepts low-voltage differential-signal (LVDS) clock and data inputs for Clock Synthesis for 622Mbps interfacing with high-speed digital circuitry, and deliv- 215mW Power ers a 3.3V PECL serial-data output. A fully integrated PLL synthesizes an internal 622Mbps serial clock from Multiple Clock Reference Frequencies a 155.52MHz, 77.76MHz, 51.84MHz, or 38.88MHz ref- (155.52MHz, 77.76MHz, 51.84MHz, 38.88MHz) erence clock. LVDS Parallel Clock and Data Inputs The MAX3693 is available in the extended temperature range (-40C to +85C), in a 32-pin TQFP package.
