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 inter-
nal 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.
