EN PHY2DAC2 200 MHz Clock Generation 100 MHz CDCLVD2102 ADC2 CDCLVD2102 SCAS904A –MAY 2010–REVISED JUNE 2010 Dual 1:2 Low Additive Jitter LVDS Buffer Check for Samples: CDCLVD2102 1FEATURES DESCRIPTION? Dual 1:2 Differential Buffer ? Low Additive Jitter 300 fs RMS in 10-kHz to The CDCLVD2102 clock buffer distributes two clock inputs (IN0, IN1) to a total of 4 pairs of differential20-MHz LVDS clock outputs (OUT0, OUT3). Each buffer block ? Low Within Bank Output Skew of 15 ps (Max) consists of one input and 2 LVDS outputs. The inputs ? Universal Inputs Accept LVDS, LVPECL, can either be LVDS, LVPECL, or LVCMOS. LVCMOS The CDCLVD2102 is specifically designed for driving ? One Input Dedicated for Two Outputs 50-Ω transmission lines. If driving the inputs in single ? Total of 4 LVDS Outputs, ANSI EIA/TIA-644A ended mode, the appropriate bias voltage (V AC_REF ) Standard Compatible should be applied to the unused negative input pin. ? Clock Frequency up to 800 MHz Using the control pin (EN), outputs can be either disabled or enabled. If the EN pin is left open two? 2.375–2.625V Device Power Supply buffers with all outputs are enabled, if switched to a ? LVDS Reference Voltage, VAC_REF, Available for logical 0 both buffers with all outputs are disabled Capacitive Coupled Inputs (static logical 0), if switched to a logical 1, one ? Industrial Temperature Range –40°C to 85°C buffer with two outputs is disabled and another buffer with two outputs is enabled. The part supports a fail? Packaged in 3mm × 3mm 16-Pin QFN (RGT) safe function. It incorporates an input hysteresis, ? ESD Protection Exceeds 3 kV HBM, 1 kV CDM which prevents random oscillation of the outputs in absence of an input signal. APPLICATIONS The device operates in 2.5V supply environment and? Telecommunications/Networking is characterized from –40°C to 85°C (ambient ? Medical Imaging temperature). The CDCLVD2102 is packaged in ?
