CS5821

www.DataSheet4U.com Century Semiconductor Inc. GENERAL DESCRIPTION CS5821 receives three LVDS data channels and one LVDS clock channel. Each data channel is deserialized into 7-bit parallel data bus for output. The clock channel is used for frame sync and fed into an internal PLL that generates the 7X serial clock used in the deserializer. A digital phase alignment circuit can generate the sampling clock of the deserializer front-end. The frame sync clock aligned to the output 7-bit data is also output for timing reference. CS5821 supports open-safe design of LVDS when the input is not connected to LVDS drivers and the receiver outputs are forced low. Putting CS5821 into inhibit mode by a shutdown control (SHTDNN) signal can lower power consumption. FEATURES CS5821 21:3 LVDS Receiver Three 7-bit serial data LVDS channels and one clock LVDS channel. Compatible with ANSI TIA/EIA-644 LVDS standard. Wide serial clocking speed ranges from 31MHz to 68MHz. Support open-safe LVDS design. Fully integrated on-chip PLL and digital phase alignment provide accurate deserializer operation. Support power-down mode. 5V/3.3V tolerant data input. Single 3.3V supply operation. CMOS low power consumption. Functional compatible with DS90CF364 and SN75LVDS86. Available in 48-pin TSSOP package.
