MAX9169/MAX9170 19-2616 Rev 0 10/02 4-Port LVDS and LVTTL-to-LVDS Repeaters General Description Features The MAX9169/MAX9170 low-jitter, low-voltage differen- 150ps (max) Pulse Skew tial signaling LVDS/LVTTL-to-LVDS repeaters are ideal 200ps (max) Added Deterministic Jitter at P-P for applications that require high-speed data or clock 23 630Mbps (2 - 1) PRBS Pattern distribution while minimizing power, space, and noise. 8ps (max) Added Random Jitter The devices accept a single LVDS (MAX9169) or LVTTL RMS (MAX9170) input and repeat the input at four LVDS out- 120ps (max) Channel-to-Channel Skew puts. Each differential output drives 100 , allowing 630Mbps Data Rate point-to-point distribution of signals on transmission lines with 100 termination at the receiver input. The Conforms to ANSI EIA/TIA-644 LVDS Standard MAX9169 and MAX9170 are pin compatible with the 30mA (max) (MAX9169), 25mA (max) (MAX9170) SN65LVDS104 and SN65LVDS105, respectively, and Supply Current, a 15% Improvement vs. offer improved pulse-skew performance. Competition Ultra-low 150ps (max) pulse skew and 200ps (max) P-P LVDS (MAX9169) or +5V Tolerant LVTTL/LVCMOS added deterministic jitter ensure reliable communica- (MAX9170) Input Versions tion in high-speed links that are highly sensitive to tim- ing error, especially those incorporating clock-and-data Fail-Safe Circuit Sets Output High for Undriven recovery or serializers and deserializers. The high- Differential Input speed switching performance guarantees 630Mbps Output Rated for 10pF Load data rate and less than 120ps channel-to-channel skew Individual Output Enables over the 3.0V to 3.6V operating supply range. Supply current is 30mA (max) for the MAX9169, and Single 3.3V Supply 25mA (max) for the MAX9170. LVDS inputs and outputs Improved Second Source of the SN65LVDS104 conform to the ANSI EIA/TIA-644 standard. A fail-safe (MAX9169)/SN65LVDS105 (MAX9170) feature on the MAX9169 sets the output high when the 16-Pin SO and TSSOP Packages input is undriven and open, terminated, or shorted. The MAX9169/MAX9170 are offered in 16-pin TSSOP and SO packages, and operate over an extended -40C to Ordering Information +85C temperature range.
